We're fans of the O-FIT insoles, which cushion our feet with strategically placed pods and support our arches and insteps for all-day comfort on our feet. The soft nubuck leather hugs our feet while a waterproof-breathable membrane adds all-weather protection for puddles, rain, and snow. This is the wide version of the Sypes, which keeps things snug in the heel to prevent slippage while adding width in the forefoot and toe box for a roomier fit.
