The mid-height version of Merrell's endless summer essential is now an even better match for summer spritzers or downpours with the addition of an Aegis antimicrobial-treated GORE-TEX lining to the GORE-TEX construction of the leather-reinforced breathable mesh upper. Merrell air cushion in the midsole. Vibram Multi-Sport Plus sole increases braking power at the heel for more demanding terrain.
