Running all winter takes a lot—extra motivation, tireless dedication, and in the worst conditions, the right pair of shoes. The ICE+ makes it easier to get out there on days that would otherwise confine you to the treadmill with a Vibram Arctic Grip outsole that can grab ice without tearing up bare roads like a spiked sole would. Overall, the neutral shoe’s fit is comfortable, with a flexible overall ride and extra cushioning in the forefoot, plus a heel fit praised by women on our test team for how well it locks the heel into place. A water-resistant upper fends off the snow, even when you’re breaking new trail. But for summer trail runs, the regular Saucony Peregrine is equally capable, bringing the same deep, lugged outsole and cushioned platform to a shoe with a more breathable upper.
