These shoes are extremely comfortable.  They do run somewhat long and narrow.  My normal size is an 8 1/2 or 9 AA, and the 8 M fits fine.  They have an adjustable Velcro strap at the instep which allows me to adjust the width even more.  They stay on my feet very well and have great foot support. The fit and comfort is much like the Skechers Reggae Rasta thong.  I have worn out two pairs of those and was thrilled to find the same fit and comfort in a different style.
