The Saucony Peregrine has been a fixture in the trail running community for years, and the 16th version brings two meaningful changes to the formula: a partnership with Vibram for the outsole and an additional 4mm of PWRRUN foam underfoot. Those two moves address the two most consistent criticisms of previous Peregrines, grip in technical conditions and cushioning on longer efforts, while keeping the core character of the shoe largely intact. The result is a trail shoe that handles a wider range of conditions and distances than its predecessors without fundamentally changing what made the line popular in the first place. I’ve been running in the Peregrine 16 on everything from technical singletrack to mixed dirt and road, and the picture that emerges is of a capable, versatile trail shoe that earns its keep on a daily basis.

Upper
The high-strength mesh upper carries protective overlays in the high-abrasion zones and a beefier toe guard that wraps both medially and laterally for better edge protection on rocky terrain. A D-ring lace anchor on each side makes the shoe gaiter-compatible, which is a useful addition for runners spending time in muddy or snowy conditions. Fit runs large, noticeably so, with some runners reporting a half size to a full size more volume than comparable trail shoes, so sizing down before your first run is worth considering, and those with narrower feet may notice some lateral movement on highly technical terrain at speed. The semi-attached tongue with its stretch construction keeps debris from entering the shoe without adding excess bulk, and the structured heel counter holds the rear foot securely in place across varied terrain.
Midsole
PWRRUN is Saucony’s EVA-based trail foam, and in the Peregrine 16 it’s been given 4mm more stack than the previous version, bringing it to 32mm in the heel and 28mm in the forefoot. That increase is meaningful on longer efforts and multi-hour outings where earlier Peregrines could start to feel thin and punishing underfoot, and it’s been achieved without pushing the shoe into the soft, disconnected territory that many trail runners actively avoid. A woven fabric rock plate sits in the forefoot to deflect sharp debris while maintaining enough flexibility for natural foot movement on more forgiving surfaces. The PWRRUN+ sockliner adds a layer of premium foam comfort directly underfoot, holds its shape well over accumulated miles, and contributes to a consistent ride feel across a long training block.
Outsole
The move to Vibram MegaGrip is the headline change on the Peregrine 16, and it delivers on its promise. Vibram MegaGrip is a high-friction rubber compound developed specifically for demanding outdoor terrain, and its reputation for grip on wet and technical surfaces is well-earned and fully on display here. The 4mm chevron-shaped Traction Lugs are directionally oriented, forward-facing for climbing traction and reverse-facing for braking control, and the compound holds confidently across loose dirt, wet roots, rocks, and snow-covered surfaces in a way the previous outsole couldn’t always match. The one mild caveat is that at 4mm the lugs are shallower than the outgoing version’s 5mm, which some reviewers noticed in deep mud, though the compound quality largely compensates for what the depth gives up.
Performance Review
On the trail the Peregrine 16 is a confident, capable shoe that handles a wider variety of terrain than most in its category. The Vibram MegaGrip provides the kind of traction that lets you run with genuine confidence rather than constantly managing your foot placement, and on technical descents and wet surfaces that difference is felt immediately. The additional cushioning from the revised midsole pays real dividends on longer efforts where the previous Peregrine could start to feel harsh underfoot, and the forefoot rock plate does its job quietly on sharper debris without deadening the trail feel entirely. For daily trail training across varied terrain, this shoe covers a lot of ground effectively and without drama.
Where the Peregrine 16 is less compelling is on the most aggressive, technical terrain where a precise, locked-down fit matters most. The roomy toe box and generous sizing can allow some lateral foot movement at high speed on narrow singletrack, and runners who prefer a more minimalist, close-to-ground feel may find the added stack height creates a slightly more disconnected relationship with the terrain than they want. The removal of the 360-degree rand from the previous version also leaves slightly less overall upper protection on particularly jagged rocky terrain. At $145 with Vibram rubber underfoot it’s priced competitively for what it offers, and as a versatile daily trail trainer for moderate to technical use it represents strong value for the majority of trail runners.
Overall Conclusion
The Saucony Peregrine 16 is a well-rounded upgrade that addresses the previous version’s two most legitimate weaknesses without losing the reliable, versatile character that made the line worth returning to year after year. The Vibram MegaGrip outsole is the real story here, elevating traction to a level that genuinely changes how confidently you can move on technical and wet terrain. The additional foam underfoot makes this a more comfortable option for longer trail days, and at $145 with Vibram rubber it’s one of the better-value trail shoes on the market right now. Just size down if you’re between sizes and this shoe will handle most of what the trail can throw at you.
Final Grade: 8/10
A meaningful upgrade on an already reliable trail platform, earning strong marks for its Vibram MegaGrip traction and improved cushioning, with the generous sizing and slightly shallower lugs being the only trade-offs worth noting for runners who push into more technical terrain.
