Comfortable and loving the slip-in feature!
Size: 10.5 X-Wide, Color: Navy
These slip-in shows are so convenient and comfortable, and have worked well for several months now. It's important to make sure that the size is not too small, as it can make the shoes feel like they will fall off. With the right fit, these shoes are very comfortable. The material breathes well and seems to be durable.
