I got these to replace my Reefs from last year, and for some reason I can only find this wide strap-style online.  These are slightly different than what I thought I would get, with a slightly bigger "heel", but then again - I replace my Reefs every year because the heel wears out.  I wear these while I walk into work (about 2 miles) and they give superb comfort, support, and no blisters.  HIGHLY recommended.
