About this product
The Men's Black BILLY Mountain Goat DZ is a cold-weather, AFO-friendly boot developed in collaboration with certified orthotists for use with braces, orthotics, and prosthetics. Its BILLY Double Zipper (DZ) configuration opens the boot substantially for easier entry and exit, while adjustable laces allow the fit to be customized. Scotchgard™ treatment, Thinsulate™ insulation, and a faux shearling lining add protection and warmth for colder conditions.

XLfeet Fit Note
The Mountain Goat DZ stands apart because XLfeet carries it specifically in 6E Extra Wide through men's size 14. The custom-developed last provides additional volume through multiple areas of the boot, while the removable spacer insoles allow interior depth to be adjusted. Combined with the Double Zipper construction, this makes it an especially useful cold-weather option for customers with very wide feet, AFOs, braces, or orthotics.
