I wore my old Teva Alps every day of summer for 17 years, through countless outdoor and aquatic adventures, until our new puppy tore one up. I tried replacing them with Teva Hurricanes, Chaco Z/2s and Bedrock Cairns. After at least a month in each of these I'd lament that they couldn't perform as well as my old Alps. So I was overjoyed when Teva reissued these. I've climbed mountains and swam rivers in the Premiers and the sole is better than the originals for comfort, fit and performance. I like how the straps drape symmetrically on both sides, so you can set a uniform distance (say 2 mm) for the sole to hang under your foot with each step. This keeps the bottoms of your feet dry and aired-out for a real barefoot feel. Teva should offer these in more attractive colors and let their reputation grow.
