Beautiful shoe. Nice quality. Going to reorder in a Wide. Regular runs too narrow for my feet. Hope the Wide works.

Good for the price but will not repurchase
Size: 9, Color: Grey
My husband loved these at first. Pros -easy to get on/off -stylish -comfortable -interior/exterior sole construction lasted longer than other more expensive shoes -price is great Cons -after less than a year the mouth of the shoe widened to a point where they slide off way too easy rendering them almost unwearable. -laces cannot be tightened
