The Aero Glide 4 is Salomon's max-cushion road shoe: a 41 mm heel of high-stack foam the brand's own spec sheet files under "ultra plush", built for cushioned but dynamic strides at a reasonable converted 255 g.
It suits you as the easy-day counterpart to the Aero Blaze — long runs and recovery mileage where softness is the brief — and as the road recovery shoe for trail runners already living in Salomon.
It is not a fast shoe and carries no plate; its dynamism is rocker-and-foam, not propulsion. In a category full of $180 flagships, its $160 tag is part of the pitch.
