Size: I wear 11.5 inch sneakers and these sandals fit me like a glove. Comfort: These are not necessarily plush sandals, but their fit and support make them extremely comfortable to walk on. Dry pavements and floors are no problem with these sandals. On the other hand, sometimes I slip a bit when walking on a wet floor or pavement. Color: Personally, these sandals are very dark blue. Durability: I wear them to and from the gym 3-4 days a week and they still look brand new. Overall: I think these sandals are as good or even better than what most major sports brands offer in slip on sandals. Highly recommended 5 stars
