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

Good value for the money.
Size: 9.5 Wide, Color: Beige
Comfortable right out of the box. Great style and well made. The more you wear the softer they get but maintain their overall appearance.
