This is Lems Shoes best seller shoe in a beautiful grey color. The upper is made of a breathable mesh and the outsole is rubber. Lightweight and flexible, it hits all marks for those that enjoy barefoot shoes. This pair is in good used condition. Shows some signs of wear (please see pictures) and unfortunately my dog chewed on the laces aglets. There are some faint marks in one of the heels and we lost the removable insoles - reflecting on the price. Besides those, they still have lots of life left in them and I’m only selling because we have too many shoes.
