Merrell Trail Running Shoes

Merrell Trail Running Shoes

Merrell has been making trail-specific footwear for over forty years, and the trail running range sits at the more accessible end of technical trail: well-built, grippy, and reliable without the weight penalty of the most aggressive mountain racing shoes. The range spans lightweight speed-focused models and more cushioned everyday trainers, with waterproof options across most silhouettes.

Vibram outsoles and FloatPro foam

Most Merrell trail running shoes use either Vibram TC5+ compound or Merrell's own M Select GRIP outsole, both engineered for traction on wet rock, rooted trail, and loose ground. The FloatPro foam midsole, used across newer models in the range, provides a softer, more responsive underfoot feel than earlier EVA builds. Several styles also include a rock plate between the midsole and outsole for protection on sharp, uneven terrain.

Waterproof and non-waterproof options

Merrell trail running shoes come in waterproof and non-waterproof versions, often in the same silhouette. Waterproof models use either a GORE-TEX lining or Merrell's M Select DRY membrane. For boggy, wet Irish trail conditions, the waterproof variants keep feet dry on longer efforts. Non-waterproof mesh versions drain faster, breathe better, and are the stronger choice in warmer conditions or on routes where stream crossings are intentional.

Terrain range and use cases

Merrell trail running shoes cover a broad range of use: from groomed forest trails and mixed-surface runs to more technical mountain routes. Models in the Agility Peak series are built for more demanding, technical ground with an aggressive lug pattern. Lighter models suit faster running on less technical trails and cross-country use. Most handle short stretches of tarmac between trail sections without issue.

Fit, drop, and stack height

Merrell trail running shoes typically have a low-to-moderate heel-to-toe drop, most between 6mm and 10mm, and a medium-width toe box. They generally fit true to size, though runners with wider feet may find some models on the narrower side. Stack height varies across the range: lower-profile models sit closer to the ground for proprioception, while more cushioned options provide greater protection over distance. Going half a size up is advisable if you plan to run in thicker socks.

Stocked and supported at 53 Degrees North

53 Degrees North is an official Merrell stockist and has been an Irish-owned specialist outdoor retailer for over twenty years. The trail running range is available in store in Dublin and Cork, where staff can help match the right model to your terrain, gait, and foot shape. Trail running footwear is worth trying in person, as stack height, drop, and last shape affect performance more than they would in a road shoe.
