I like these shoes, but there is a significant width difference between these Narrow width and Wide width shoes.  I have a wide, flat 10 to 10.5 foot and while Wide width fits great, the Narrow was way too tight. I had to return for wide width.

Other than that, these are comfortable shoes that usually do not slip off.  I have an Achilles tendon injury and needed backless shoes. I wear both of the shoes for short walks or the left shoe + Even up (shoe riser) and my right foot in an Aircast and both feel good.
