The Genesis 2 updates Salomon's most popular modern trail trainer where the ground actually tests it: a fully integrated activeCHASSIS and a wider midsole platform for stability, reworked lug geometry on the contaGRIP outsole — 4 mm lugs — and the durable Matryx upper carried over.
It suits you for serious trail running on rocky and technical terrain at training effort: the one-shoe answer for trail runners who are not shopping by race distance.
It is not an ultra hauler or a racer — the chassis is guidance, not propulsion — and its heel stack prints as a decimal (33.5 mm) on the brand page, so no stack figure appears here. At about 283 g it is the sensible weight for what it does.
