Dr. Comfort Men's Ranger Lace-Up Boots are so easy to adjust - no tying or untying laces required! This rugged lace-up boot simplifies adjustability. You don't have to tie the elastic lacesthey stretch for an easy fit. The leather upper also features an adjustable hook-and-loop ankle strap, so you can further customize the fit. Plus, it has a padded tongue and collar that feel soft against your foot. Need more a personalized feel? Remove the microfiber-lined insole and replace it with your own orthotic. Leave it in for layers of comfort underfoot. A bottom layer of polyurethane offers support, while the polyethylene top layer cushions from heel to toe. Gel pods in the forefoot and heel add extra cushioning right where you need it. Orthotic and Diabetic-Friendly.
