Puma El Ace LeatherThe Puma El Ace is essentially the lace-up version of the popular Puma El Rey slip-on. This casual sneaker features a simple vulcanized style with a rubber outsole, subtle Puma branding, and a rubber accent strap that is part of the lace-up design. It's hard to look at this model and not think of the cool and casual days of spring/summer. Lace them up and chill.
