Pulsar is the shoe Salomon points at a hard trail effort. It sits low, with a 6 mm drop and a 29 mm heel, so you feel the ground and can react to it — which is the whole point on rocky, technical running, where a tall shoe rolls you around instead.
It suits you if you have a weekly trail session or a short race in mind and want grip you can trust the moment you commit to a foot placement.
It is not a long-day shoe. At 281 g it is heavier than the low stack suggests, and there is less foam between you and the rock than an ultra runner wants at hour four. Keep something taller for the all-day efforts.
