Mizuno Issues Sole Thickness Correction to July 1 Press Release for New Wave Duel Neo Shoe



On Aug. 11 Mizuno issued corrections to  a press release originally dated July 1 announcing that its all-white prototype model containing the new Mizuno Enerzy foam was being released under the name Wave Duel Neo. On its third page the updated press release corrected specifications for the shoes' sole thickness. The company apologized for any inconvenience caused by inaccurate specifications in the previous versions of the release.

On July 28, World Athletics announced new regulations governing the sole thickness of shoes used in track and field competition. The new rules specified the method by which sole thickness was to be measured. Previously, sole thickness was measured from the outsole to the midsole. The new World Athletics regulations specified that in addition to the outsole and midsole, the inner sole and insert were also to be included in measurements of thickness.

In accordance with the new regulations, Mizuno amended the specifications of both the Wave Duel Neo and Wave Duel Neo Low versions of the new model. Prior to the amendment, forefoot thickness was listed as 14 mm and heel thickness as 23 mm. Under the revised regulations, forefoot thickness for the new model is now listed as 20 mm and heel thickness as 27.5 mm.

Please see the revised official press release for further information.

Translator's note: The new WA regulations prohibit shoes with a thickness of greater than 25 mm from being used in track competition. Mizuno's press release proudly mentions that Soka University's Yudai Shimazu broke the course record for the anchor stage at this year's Hakone Ekiden while wearing the prototype model of this shoe. Junichi Ushiyama, an amateur runner who ran 28:58.89 for 10000 m last November, tweeted a suggestion that Mizuno sell the Wave Duel Neo without insoles to hit 25 mm and market socks with a thicker sole to be used instead. No doubt this wouldn't work, but it's an indication of the frustration and confusion the sudden imposition of the new regulations has caused.

Waseda Leads Top 7 Teams Under Izumo Ekiden CR, Ivy League Best-Ever 3rd (updated)

3rd last year, Waseda University scored its first Izumo Ekiden win since 2010, taking almost 2 minutes off the CR and leading the top 7 teams under the old record of 2:07:51 for the complete 6-stage, 45.1 km course. Waseda was 16 seconds back in 7th after the First Stage, but its 2nd runner Ojiro Honda made that up easily and put them 6 seconds out front. A massive 22:56 CR for the 8.5 km Third Stage by Shadrack Kipkemei (Nihon Univ.) dropped Waseda back to 2nd even though its runner Ryuki Suzuki broke the old CR too, but back-to-back CR on the next 2 stages by 1st-year Haruki Niizuma and Shunpei Yamaguchi put anchor Shinsaku Kudo out of reach of the rest of the field. Kudo duly won the 10.2 km anchor stage in 29:00, bypassing a 2:06 time entirely for a new 2:05:56 CR, just under 2:48/km average pace for the complete course. Defending champ Koku Gakuin University struggled a bit in the first half of the race but came on strong in the longer second half with 4th and 5th runners...

Kipyegon Repeats, Toyo Wins Hakone Ekiden Qualifier in First Appearance in 21 Years

Back for the first time in 21 years after a disastrous 14th-place finish at the 102nd Hakone Ekiden this past January, Toyo University hit one out of western Tokyo's Showa Kinen Park with a solid win at the Hakone Ekiden Yosenkai, the half marathon that serves as the official qualifying race for the 103rd Hakone Ekiden. The top 10 teams in the Hakone auto-qualify for the following year, with the rest having to run the Yosenkai in October with a squad of 10 to 16 runners out of which the top 10 score on aggregate time, with the 10 fastest schools joining the Hakone field and top individuals from non-qualifying teams names to the Kanto Region Student Alliance select team to make up the complete Hakone field of 21. Driven in large part by an aggressive run from 3rd-year Yu Miyazaki , one of only 2 Japanese athletes to go with the big African contingent up front, Toyo won in 10:31:30, 1:03:09 or 2:59.6/km per athlete. As the first team to have broken the 3:00/km average pace barrie...

Ngetich and Mutiso Take Down Tokyo Legacy Half CR

In its 5th edition the Tokyo Legacy Half Marathon scored 2 new course records via Kenyans from the Ikaika agency, with 10 km WR holder Agnes Ngetich blasting 3 minutes off the old record to win by over 4 in 1:04:23, and Alexander Mutiso skimming just 1 second under the CR for the win by 5 seconds in 59:51. The 2 races played out completely differently, even if the paydays were the same for the winners. Surrounded by an envelope of male runners all the way to the final 100 m, Ngetich was out hard on the downhill in the first 5 km, hitting it on sub-64 pace in 15:08 before leveling out on the flat middle 10 km. Her next 2 splits projected to 1:04:09 and 1:04:17, and even with the uphill back to the stadium in the last 5 km she didn't fall far off from that, winning in 1:04:23. Runner-up Tabitha Njeri Kamau was nearly a mile back in 1:08:28, with Kamau's Mitsui Sumitomo Kaijo teammate Kazuna Kanetomo dropping a 1:10:17 PB for 3rd. Now an independent, track Olympian Kaede Ha...
