Surrounding a weatherproof eVent bootie construction is everything you love about the classic Lone Peak plus the new addition of the responsive Altra EGO midsole. A grippy MaxTrac outsole keeps you conquering rough terrain while the GaiterTrap keeps debris at bay. Plus, we've tacked on an external TPU heel for added support, protection, and durability. With the Lone Peak ALL-WTHR, you can go fast and make a splash, all while keeping dry.
