I returned these shoes as the design is so odd that I could not wear them.  I think if you have a very narrow flat foot  they might be ok.  I usually wear between an 8 ½ and a 9 so I ordered a 9 to be safe since it's hot and my feet tend to swell.  The shoe was very tight and narrow.  So I let my daughter try them who wears between an 8 and 8 ½  the top strap was too tight, but the bottom strap was too loose.  Like I said ... Very oddly designed shoe.  But if you have the correct foot shape they would be super comfortable to walk in.  The footbed of the shoe was super comfy!!
