I was drawn to these sandals by the cushiony, memory-foam-ish padding and their availability in narrow sizes. I usually wear a 9.5 in most brands and have narrow feet. While the 9.5 N in the Margie Sandal is a perfect fit in length and width, the shoe is only comfortable if I am standing still. The design of the straps makes it one of the most frustrating shoes I own. If I am walking on an ever so slight decline, my feet slide all the way to the front until my ankle hits the first leather X. My toes are then off the shoe, the back strap slides off and I have to re-adjust them every other step. URGH. Walking on a real decline is practically impossible. The back strap also slides off regularly, and I have to *think* about how I am walking so that the shoes stay on my feet. Any shoe that requires mental effort to keep them on is not worth my while. I so wish I could return them, but I wore them out before trying them on around the house.
