Merrell Agility Peak 6 vs Saucony Peregrine 16

Two grippy, protective trail all-rounders at the same weight. The Agility Peak 6 has deeper lugs and a rock plate for rough, steep ground, but the ride is firm and the toe box narrow. The Peregrine 16 is £5 cheaper, nimbler and a little roomier, with more cushioning than before.

What the critics say

The reviews comparedReviewers praise the grip of both, and RunRepeat's Carlos Sánchez found both toe boxes narrow or tapered. He rated the Merrell Agility Peak 6 dependable on technical ground but found its foam flat, and Believe in the Run's testers found it firm and stiff. iRunFar's Travis Liles praised the Saucony Peregrine 16's extra cushioning and ground feel, and Sánchez found it stable.

  • Dependable and protective on technical terrain

About each shoe

About the Agility Peak 6

Merrell's Agility Peak 6 is a cushioned, versatile trail shoe for distances from 5K to ultras, and it replaces the Agility Peak 5. The midsole uses FloatPro, Merrell's EVA-based foam, with a rock plate in the forefoot for protection on rough ground.

Grip comes from a Vibram Megagrip outsole with Vibram Traction Lug technology and 5 mm lugs in chevron and butterfly shapes. Merrell gave this version a new, slimmer last, a lighter build and a web-style outsole pattern. The geometry sets a 32 mm heel and a 6 mm drop.

Compared with the Nova 4, which has an 8 mm drop, Merrell's own Quantum Grip rubber and no rock plate, the Agility Peak 6 is the more aggressive, more protective option. Men's sizes come in standard and wide fittings, and a GORE-TEX version, the Agility Peak 6 GORE-TEX, is available for runners after waterproof running shoes.

About the Peregrine 16

Saucony's neutral trail all-rounder, the Peregrine 16, is built for moderate, mixed terrain. It is lower and lighter than the long-distance Xodus Ultra 4, which uses a PWRRUN PB midsole, while the Ride TR3 covers lighter road-to-trail use on gravel and towpaths.

The big change for this version is the outsole: Vibram Megagrip with Traction Lug technology, arranged as chevrons that reverse direction between forefoot and heel. A forefoot rock plate with cutouts adds protection underfoot, a PWRRUN+ insole sits on top, and the lightweight mesh upper has a fully gusseted tongue. It has a 4 mm drop and a 32 mm heel stack. Standard and wide fittings are offered, and a GORE-TEX version, the Peregrine 16 GTX, is available for wet conditions, which also places it among waterproof running shoes. It replaces the Peregrine 15.
