Come rain or shine, it&';s divine. We all know that not every day is filled with sunshine and smiles, so we&';ve added our highly breathable B-DRY waterproof technology to the Ousel to keep feet dry on those early morning dog walks or mud season jaunts. So, stomp through those puddles in confidence! We use our own gender-specific lasts to address the anatomical nuances between different types of feet. Length runs true to size. Form hugging heel cup, sculpted mid-foot, and a generous forefoot & toe box. Width Standard - Women&';s standard width is B in the heel and C in the forefoot (according to Brannock Device). Patterns and materials in a given model may influence fit. We always recommend trying our footwear on to ensure the best possible fit. Volume Standard Medium-High volume feet tend to be wider with higher arches and insteps.
