Mizuno reveals the Hyperwarp 96 — a thick-soled racer at just 96g per shoe

At a launch event in Tokyo, Mizuno showcased the "Hyperwarp 96," a thick-soled racing shoe weighing approximately 96 grams per shoe (size 27.0cm), a striking lightweight take on the carbon-era racing category. Gizmodo Japan framed it as Mizuno "doing it again," underscoring the ongoing weight-vs-cushioning arms race among Japanese brands this fall.

Seoul's retail sector wages a full-on "runner capture" war

Korea's autumn running season has turned into a multi-industry scramble: Musinsa, Adidas and Lotte are going beyond shoe discounts to run-lace-ups with real running events and run-club communities — running-related search volume has grown 4.4x, per Segye Ilbo. Food companies are joining too: Ilhwa will supply 36,000 bottles of products across three September marathons, with Maeil Dairy and Ildong Foodis expanding sports-nutrition experiences, reports Hankyung.

Seoul city events open first-come, first-served registration

Seoul's "Seoul Runners Festival" opened first-come registration on Sept 21 at 2pm for 4,600 spots at a ₩10,000 entry fee, with a kids' run and a run-crew team competition, plus a shakeout run the day before at Yeouido Park on Oct 24 (News1). Separately, the 2026 Seoul Love Marathon opened registration Sept 22, running through Oct 31.

Marathon-season deal season on carbon super-shoes

With autumn marathons imminent, retailers are discounting heavily: TechRadar rounds up savings of up to 40% on top-rated shoes from Hoka, Brooks, Asics and Nike at Amazon.

Local view

• Japan: Beyond the Mizuno launch, Japanese outlets remain focused on niche shoe culture — VAGUE via Yahoo! News covers the surprise re-release of the Nike Zoom Streak 3 in a vivid orange as a "thin-soled" counterpoint in an era of max-thickness stack shoes, noting its outsole influenced early carbon super-shoe development. Running Street 365 also flags a campaign by Venex giving away 40 Tokyo Marathon 2027 entry spots via lottery from Sept 18 to Oct 31 — a consolation route for runners who missed general entry.
• Korea: Seoul Economic Daily reports that as weather cools, run crews are out again and demand for running apparel and shoes is surging simultaneously, citing the Ministry of Culture, Sports and Tourism's 2025 national sports survey putting Korea's running population at about 10 million.

Context & numbers

• Regulatory backdrop: World Athletics shoe regulations effective Jan 1, 2026 govern stack heights and approved-shoe compliance for competition (official regulations document; pre-cutoff but current governing framework).

On the radar

• 2026 Seoul Love Marathon registration is open until Oct 31.
• Mizuno's Hyperwarp 96 retail rollout and first independent reviews are worth watching after the Tokyo reveal.
• rumor: continued Japanese brand experimentation with ultra-light thick-soled racers could pressure the 40mm stack-height regulatory edge.
