When the snow begins to melt and the trails are muddy, I opt for dryer locales to get a workout in—mainly the gym or paved roads. This year, I bid farewell to my blown-out kicks and tried the Altra Solstice XT 2. These cross-trainers are lightweight, comfortable, and have a balanced cushion platform built in, so my feet stay supported on long road and treadmill runs. Altra’s wider toebox also offers plenty of room for my feet to breathe. $130; available at Uphill Pursuits, Schnee's, and online.
