Ethan is lightweight u-throat shoe for men. The upper is soft tumbled full grain leather with a pigskin collar lining. The midsole is made of EPR foam for a resilient feel and excellent support. The outsole pads are slip-resistant rubber. The removable footbed is made of two densities of EVA foam - the heel cup is more rigid to stabilize the heel, while the forefoot is softer for a cushy feel and flexibility where you need it. The footbed and vamp linings are both Tek-Dry®, a moisture-wicking fabric with an anti-microbial treatment. There is a removable spacer underneath the footbed that can be customized or removed to allow extra space for an orthotic. A nylon and fiberglass composite shank completes the package.
