Merrell Agility Peak 6 Boa

Merrell Agility Peak 6 Boa review: what runners say

Fit

New Skyfire last makes the fit slimmer and more secure through the midfoot and forefoot, with improved heel lockdown compared to previous versions, though some residual heel lift persists. Narrow toe box, cited by multiple sources as restrictive for those with wide forefeet.

Feel

FloatPro midsole feels stiffer and less responsive than the 5th generation, with a 'blocky' ride sensation when cold that softens after a few miles. Good ground feel and stability thanks to full-length flex connect, but limited energy return.

Durability

Vibram Megagrip outsole with 5mm lugs rated among the best in its category for compound and resistance; rubber is harder than usual, noted as ensuring greater longevity at the expense of slightly less grip on smooth surfaces. Upper features robust TPU overlays. No specific mileage data reported.

Best for

Technical all-mountain trail shoe, designed for rugged terrain, mud, and wet surfaces where grip is critical. Better suited for quick, agile runs on technical trails up to medium-short distances rather than ultradistance, where the lack of plush cushioning is noticeable.

Weak points

Midsole judged stiffer and less dynamic than the Peak 5, with poor energy return. Narrow toebox flagged by multiple reviewers as a limitation for those with wide feet.
