Hoka's Skyward X 2 reaches the on-sale window on Friday 15 May, twenty-four hours from now, with global retailers confirming a $225 and £225 price point and stocked colourways already on the racks at flagship stores in London, New York, Tokyo and Sydney. The launch follows a four-month embargo window during which World Athletics-certified review pairs went out to a small group of testers in March, and the second-generation Skyward X has shipped with two of the changes flagged in our March preview: a redesigned PEBA midsole that sheds two millimetres from the previous stack height and a carbon plate that has been re-pitched with a more aggressive forefoot rocker.

The stack drops from forty-eight millimetres in the heel and forty-three in the forefoot on the original Skyward X to a forty-six and forty-one millimetre stack on the X 2, sitting Hoka's super-trainer just inside the World Athletics legal maximum for a non-spike road shoe. The two-millimetre reduction is paired with a lighter midsole compound that Hoka calls PEBA Pro and which the brand says recovers more vertical energy on each foot strike. Tester pairs we received in March came in at two hundred and seventy-eight grams in a UK 9 men's size, down twenty-one grams from the first-generation shoe and noticeably lighter than the brand's Rocket X 2 racing shoe.

The carbon plate has moved as well. The original Skyward X used a parallel twin-plate system that Hoka has merged into a single full-length plate with a more aggressive forefoot rocker and a deeper heel scoop. The result is a shoe that feels closer to the Rocket X 2 underfoot through the toe-off phase, with reviewers consistently describing the X 2 as "more committed" than its predecessor. The trade-off has been a slight loss of stability at the rearfoot, which Hoka has addressed with a wider heel platform and a small medial post finished in the brand's signature anthracite-grey rubber.

The launch colourways at Friday's release include the standard "Frost Blue" and "Cosmic Pearl" tested through the preview window, plus a UK-exclusive "Lakes" colourway in deep green and a US-exclusive "Solar Flare" in coral and yellow that draws on Hoka's Olympic team kit from last summer. Retailers contacted by Running Lookout overnight confirm full size runs from UK 4 to UK 14 in the men's range and UK 3 to UK 10 in the women's range, with stock holding stable through the weekend before a planned restock window in early June. The shoe is launching online at hoka.com and through specialist running retailers including Runners Need, JackRabbit and the Running Warehouse.

The Skyward X 2 sits in Hoka's "super-trainer" line alongside the Mach X 3 and below the Rocket X 2 racing flagship, and Hoka is pitching the shoe firmly at high-mileage marathon training rather than racing. Hoka's elite team will not race in the X 2; Olympic marathon medallist Hellen Obiri and 100-kilometre world record holder Charlie Lawrence will continue to train in the X 2 but race in the Rocket X 2 through the autumn marathon block. Reviews from the embargo window go live in parallel with the Friday launch, and Running Lookout will post a full multi-tester review across the weekend.
