The great outdoors needs great footwear. Engineered for trail/cross-country walking (with sport-utility looks suited to city streets too), FitFlop's Neo-D-Hyker has been reworked for a cleaner aesthetic and enhanced perfomance in extreme conditions. The fully waterproof build keeps you dry in heavy rain/wet snow. With 3M Thinsulate insulation so feet stay warm when it's sub-zero and debuting FitFlop's grippiest ever outsoles for safer walking on rough, steep or wintry surfaces. Wraparound rubber mudguards and bellows tongues (designed to stop water/debris entering) add extra protection. Here in non-wicking recycled endurance fabric and water-repellant suede, these combine sneaker-like lightness, flexibility, comfort, with the stability and security of trail shoes. Adjustable padded uppers and anatomically contoured footbeds provide support over long distances. On FitFlop's Neodynamic midsole: high-rebound, impact-reducing cushioning, featuring a springy central carbon plate that propels you forward and smooths out movement heel to toe. Wear for rural strolls, urban exploring, forest hikes, hill walks, winter treks, off-trail expeditions... (This boot version gives added ankle support/protection.)
