Salomon S/LAB Genesis 2 Review: Why Is It Sold Out in Men's Sizes? I Measured It

Here in Japan, where I'm based, the official Salomon store sold out of nearly every men's size of the S/LAB Genesis 2 within about two weeks of launch. I bought a pair ($200, US MSRP), weighed it, measured the insoles against a Novablast 6, and took it out on gravel and rough ground. Then I dug into WHY it's so hard to get. ▼ Measured results (US men's 7.5 = UK 7 / EU 40⅔ / JP 25.5 cm, one shoe) • Weight: 8.7 oz (247.0 g) — claimed 9.6 oz (272 g) • Insole width, forefoot: Genesis 2 88 mm vs Novablast 6 91 mm (−3 mm) • Insole width, midfoot: Genesis 2 71 mm vs Novablast 6 80 mm (−9 mm ← this is where it feels snug) • Stack 31 / 25 mm (6 mm drop) · Lugs 4.5 mm · +39% ground contact vs. the original (Salomon's figure) · One unisex colorway (Black / Black / Fiery Red) ▼ Chapters 0:00 Opening 0:18 Who I am 0:30 Sold out in men's sizes?
