Shoe Review: Relance RL-01



JRN hasn't done many product reviews over the years, but when French shoe startup Relance contacted us about reviewing their RL-01 model we liked what the company's mission statement had to say about manufacturing domestically, environmental concerns and paying workers a fair wage, and agreed to try a  pair.

Relance was launched in late 2019 by designer Violaine Grégoire. The RL-01 is the first shoe she and her team have brought to market. Still in the Kickstarter phase, Relance hopes that the RL-01's limited release will help generate the funds and interest needed to launch full-scale production and additional models next year.

The Shoe

At first glance the RL-01 looks like what it is, a heavy cushioned trainer geared toward fashion-conscious recreational runners. It's got a lot of nice styling details like a blue-white-red tricolour logo and heel loop, and a single pair of differently-colored eyelets, but weighing in at 330 g it's definitely on the heavier end of the spectrum. PR materials claimed a 10 mm drop on the shoe, which seemed accurate.


The Upper

The upper is a thick knit mesh that the company's site describes as minimizing wasted material during the manufacturing process, with only a single seam on the outside rear of the heel. Everything behind the arch of the foot is enclosed in a rigid heel cup with a thick ankle cuff. Despite what seemed like minimal ventilation, even though I did all the test runs on the shoe in the middle of the heat and humidity of a Tokyo August, the RL-01 never felt too hot or lacking in breathability.

One thing I didn't like was a seam running down both sides of the inside liner just ahead of the arch end of the heel cup. There was a loose forward-facing flap of material just ahead of where the seam was stitched that seemed like it would have the potential for irritation on longer runs. I felt like these could easily be stitched better to eliminate the flap of extra material. 

A white strip down the middle of the tongue kept the laces in place and prevented any tongue slippage. The outside of the heel featured the only reflective material on the shoe, a stitched-on faux leather silver wedge. Rather than high-visibility it is simply shiny, and while it looks good it seemed like unnecessary weight and unbreathable material that could be replaced with lighter, higher-visibility material.

The Midsole

The midsole is a single layer of curved foam about 15 mm thick under the ball of the foot and 24 mm under the heel, extending back an extra 5 mm behind the vertical line of the heel. No details on the material were available, but it had a good feel. For reference, the last few months I've been running in the On Cloudflyer, Karhu Fusion 2021 and Mizuno Wave Rider 24. I'd categorize the Cloudflyer as hard, the Fusion as firm (i.e. hard but some responsiveness) and the Wave Rider soft. The RL-01's midsole is on the responsive side of firm relative to the Fusion. On both the inside and outside of the arch it's thicker, but under the foot it's the same level as in the forefoot and heel, meaning there's a saddleback that offers some stability without higher-density foam or other mechanisms.



The Outsole

The outsole is a bit of throwback by today's standards, a single layer of thick, hard polyurethane that leaves none of the midsole material exposed to the pavement. About 3 mm thick along most of the shoe, in the heel it's about 14 mm at its thickest point on both the inside and outside of the heel. The forefoot and heel feature a tread pattern of protruding triangles and wedges that reminded me of Newton's technology as they seemed to take the initial impact with the road surface and to compress a little before the rest of the sole made contact.

The Insole

When I pulled it out he insole was one of the bigger surprises and seemed to have the highest level of engineering in the shoe. Made up of four different densities of foam, it looks more like an insole you might buy separately rather than what you'd usually expect to come pre-installed. 

The non-impact parts of the forefoot and the upper edge all the way around are a light foam material, with a denser silicone wedge under the ball of the foot that actually stands out slightly on the top of the insole. The arch and heel are a harder foam that extends upward on both sides to continue the lines of the midsole in the arch. Directly under the heel on both the top and bottom of the insole is a very soft and thick oval of additional cushioning.



First Feel

On first feel on the foot, the RL-01 was very roomy but surprisingly comfortable. Even just standing the drop was noticeable. The sizing on the box was what I usually wear, but it felt like I could have gone at least a half size smaller, maybe a full size. On the first two runs I had to tie it much tighter than I usually would in order to feel like it wasn't sliding around, which created some discomfort on the front of the ankle. From the third run on I switched to thicker socks, which made the fit feel pretty much right through the heel and ankle, but still left the toe box feeling too big. The shoe being a little too big probably contributed to it feeling well-ventilated and may have prevented irritation by the loose seams mentioned above. 

The Run

I did about 50 km in the RL-01 prior to this review, 40 km on pavement and 10 km on soft surfaces, ranging from about 4:00/km to 6:30/km with a longest run of 16 km. From the first run they felt lighter than their 330 g weight, especially in comparison to comparable cushioned trainer models from other makers. Once I got the sock and lace tightness worked out to compensate for the shoes being a bit too big they handled well and were notably stable on sharp corners. Even on the longest run the sense of them being lighter than they were held up.

The interaction between the midsole and insole was a lot more pronounced than in other shoes I've run in in recent years, the midsole firm but responsive as above and the insole adding a noticeable layer of cushioning and return. At slower paces the heel unit felt well-designed to accommodate heel striking, in particular the extra-thick oval in the insole. I was concerned that the edge of the oval would be irritating as that part of the foot doesn't usually come into contact with a seam or edge, but I never actually felt it. 


The similar elevated pad on the top of the forefoot was noticeable, though, and its leading edge came right where the pad of the big toe starts to curve toward the joint. It might have been a product of the shoe being a half size too big, but the placement was a constant irritation on the first few runs; not enough to rub and cause blisters but an odd sensation where you wouldn't normally have one. Once I switched to thicker socks it wasn't noticeable any more.

The faster-paced runs were probably the biggest surprise, as the responsiveness of the midsole foam made for surprisingly comfortable forefoot running. My sense is that the high construction of the arch in the midsole and insole encouraged this. At moderate and slower paces the thickness and rigidity of the arch was prominent and could be another source of irritation for anyone with a relatively low arch or flat foot, but at higher paces it seemed to encourage the foot  to roll a little further forward. Summer in Tokyo and where I am in my fitness right now precluded doing anything faster or longer within the window I had, but while the shoe is clearly not intended for speedwork I'd like to try it out on something more in the 3:30/km range. Likewise for a 30 km long run.

I also didn't have the chance to try the RL-01 on wet pavement, but the tread's grip on both dry pavement and dirt trails seemed good and I wouldn't expect slipperiness to be an issue.



Quality

After 50 km the hard polyurethane outsole showed no sign of wear or abrasion. The only clear sign of any wear was the hexagonal Relance logo printed on the heel of the insole being partially worn off on one foot. It seemed like the adhesive between the heel cup and inner liner may have started to come unstuck after 50 km, but I didn't notice its initial state so I'm not sure how much it may have changed, and in case it wasn't noticeable unless you examined it very closely and not at all while running.

Overall

For a first-time product from a company that has been in existence for less than two years the RL-01 is a good debut. I can certainly think of a few makers that took a lot longer to reach a comparable level. It's not perfect, and in its current form might be best for the curious and people who like to have the newest whatever. But it shows potential, and if Relance's Kickstarter campaign, which offers backers the chance to try the RL-01 at a pre-market price, is successful there'll hopefully be an updated model with the kinks ironed out on the way next year. There's no indication of plans for a performance model, but one step at a time.

Hokkaido's Asahikawa Ryukoku H.S. Builds 330 m Greenhouse Indoor Track

Targeting its sixth-straight win at the Oct. 23 Hokkaido Prefecture High School Girls Ekiden, Asahikawa Ryukoku H.S. has complete construction of the Asahikawa Ryukoku Indoor Track, at 330 m in length the nation's largest running-specific circuit course entirelyely enclosed in vinyl greenhouse material. The ceremony marking the track's official completion is scheduled for Oct. 28th. In a part of the country known for heavy snowfall, the hope is that Asahikawa Ryukoku's new year-round training ground will help it make the jump to becoming a factor at the national level. The indoor track was built on the 1650 square meter campus of the former Asahikawa Toei H.S., where Asahikawa Ryukoku H.S. will relocate next summer. Coated in durable vinyl, the massive white torus of the track stands out from its surroundings. Ranging from 5.4 m to 7.2 m in width, the track's housing is wide enough to accommodate four lanes. In the future, two lanes will be covered with artificial turf

Meiji University Wins Hakone Ekiden Qualifier Half Marathon

After a surprise finish outside the top 10 at this year's Hakone Ekiden, Meiji University  was back to do the expected, winning the Hakone Ekiden Yosenkai half marathon qualifier Saturday in Tachikawa, Tokyo by over 4 minutes. In windy conditions things went out slowly up front, the lead group of 6 Kenyans hitting the first km in only 3:01. Last year's winner Joseph Lemeteki Razini  (Takushoku Univ.) made a push to get things into gear and Vincent Raimoi (Kokushikan Univ.), James Bunuka  (Surugadai Univ.), Charles Kamau Wanjiku  (Musashino Gakuin Univ.) and Paul Onyiego  (Yamanashi Gakuin Univ.) all took turns leading, but it wasn't until 14 km for Wanjiku to make a serous move. Running the rest of the way unchallenged, he took 1st in 1:01:23, more than a minute slower than Razini's winning time last year. The only two people in the front group not to take the lead at some point, Samson Ndirangu (Ryutsu Keizai Univ.) and Noah Kiplimo  (Nihon Yakka Univ.) were 2nd an

Championship Ekiden Qualification Weekend

Championship ekiden season is on the way, and this weekend two of the main events will hold their official qualification races. Saturday in Tokyo's western suburb of Tachikawa is the Hakone Ekiden Yosenkai half marathon, a chance for collegiate men to be on the starting line of the world's #1 race this coming January. 10 universities are already qualified for the Hakone Ekiden by having finished in the top 10 at this year's race, and at the Yosenkai another 10 will join them. 41 universities from the greater Tokyo area will run from 10 to 12 men each and are scored on the total time of their first 10 finishers. The fastest 10 teams go on to Hakone, pure and simple. Top individuals from teams that don't qualify will also be named to a select team, as long as they're Japanese citizens, to fill out Hakone's field of 21. NTV will broadcast the race and its tense qualifier announcement ceremony live starting at 9:25 a.m. Saturday local time, with official streami
