About this product
The Men's Black Leather BILLY Cozy Goat DZ is an AFO-friendly high-top designed in collaboration with certified orthotists for use with braces, orthotics, and prosthetics. Its BILLY Double Zipper (DZ) configuration creates a wide opening for easier entry and exit, while adjustable laces allow the fit to be customized. A leather upper, fleece lining, Thinsulate™ insulation, and Scotchgard™ treatment make the Cozy Goat particularly well suited to cooler weather.

XLfeet Fit Note
The Black Leather BILLY Cozy Goat DZ is especially notable because XLfeet carries it specifically in 6E Extra Wide through men's size 14. Its custom-developed last provides additional volume through the toe box, vamp, quarter, and heel, while multiple removable insoles allow the interior depth to be adjusted. The Double Zipper construction creates a substantially wider opening than a conventional lace-up high-top, which can be particularly beneficial for AFO and brace users.
