Agility Peak 6 vs Ultra Glide 4

The Agility Peak 6 is Merrell's do-it-all trail running shoe, the one you reach for when the route mixes mud, rock and long slow miles. It sits in the cushioned-but-planted camp: a generous FloatPro midsole under an aggressive 5mm Vibram Megagrip outsole, with an 8mm drop and a 38mm heel stack that soaks up rough ground without floating you off it. This is not a racer and it does not pretend to be. It is a dependable daily trail trainer built for grip, protection and staying comfortable when the run drags on. We rate it as one of the best value all-rounders in its class, and RunRepeat's 84/100 backs that up. If your trails are technical, wet or steep and you want one shoe that copes with all of it, the Agility Peak 6 is an easy shoe to recommend. Compared with the pricier Hoka Speedgoat 7, it trades a little plushness for a firmer, more connected feel underfoot.

The Ultra Glide 4 is Salomon's soft, high-stack trail runner built for one thing above all: keeping your legs fresh over long, rolling miles. With 38.6mm of heel stack and a moderate 7.5mm drop, it sits firmly in the cushioned trail shoe camp, closer to a plush daily trail cruiser than a nimble racer. At 295g it is not the lightest option out there, but that weight buys you a genuinely comfortable, protective ride that soaks up rocky, uneven ground on the way home from a big day out. This is a shoe for runners who value comfort and easy-going stability over sharp, aggressive handling. It thrives on smoother, non-technical trails, gravel, forest paths and long ultra efforts where fatigue is the enemy. If you want a running shoe that lets you switch off and just log the distance, the Ultra Glide 4 makes a strong case at its £130 price.
