Aero Glide 3 vs Aero Glide 4

The Salomon Aero Glide 3 is a road-focused, max-cushioned daily training shoe from a brand better known for trail. It is a soft, protective cruiser built for easy miles and long runs rather than chasing pace. At 275g it is not a light shoe, and the 8mm drop plus deep stack put comfort and leg protection first. What you get is a stable, planted ride that keeps your legs fresh when the run drags on past an hour. This is a versatile running shoe for the runner who wants one dependable trainer for the bulk of their week, not a race-day tool. If you already know Salomon from the trails, the road manners here will surprise you. It sits in a crowded max-cushion daily market, and the Aero Glide 4 has since arrived, so at RRP the 3 is best bought on a deal.

The Salomon Aero Glide 4 is the brand's big-cushion road running shoe, built for soaking up easy miles and long runs without asking your legs for anything back. With a tall 43.2mm heel stack and no carbon plate, this is a comfort-first daily training shoe rather than a racer. What sets it apart from most max-cushion rivals is the tall 11.7mm drop, which rolls you forward off a generous heel and suits runners who land heel-first. It is not the lightest shoe in the class at 250g, and it is not trying to be snappy. What you get instead is a soft, planted, protective ride that stays comfortable when the miles pile up. If you loved the Aero Glide 3, this is a familiar, refined take on the same idea. We rate it as a dependable cushioned trainer for steady runners who value comfort over pace.
