I ordered the 4e width variety, and I have ordered other NewBalance slip on sandals of the same size though slightly different styles. This pair was far narrower than the previous version (that is no longer available through amazon). I measured this pair against the pair they are meant to replace and this pair is 3/4&#34; narrower at the widest point and about 1/2&#34; narrower at the narrowest point. They were reasonably comfortable at first, but the narrow platform made it feel like I was in danger of having the shoe &#34;tip over&#34;, or that my foot may roll off the edge.<br />The top band is adjustable, and took quite a few times to find a place where it was comfortable. I adjusted it to where it seemed to fit right but it rubbed the top of my foot and produced a blister rather quickly. I readjusted it several times and seem to have it where it will do.<br />I wouldn't recommend this for someone with ultra-wide feet like I have. Other NewBalance products have fit me better in the past and I expect and hope I will find another incarnation next year that will fit me better than these do.
