The length and width of the sole were ok, but the neoprene across the top of the foot was too constricting and there was no way to loosen it!  I am a diabetic with hammer toes and wide, fat feet and this was way too tight for me.  It left big dents on the top of my foot.  This was size 8.5, which is a wonderful size for me in the KEEN women's Voyageur shoe and pretty ok in the KEEN women's Presidio shoe, both of which I wear with the laces at about their loosest length.  My 'true' size is 7.5 wide.  (My only issue with the Presidio is that the tongue is fairly long and isn't padded where it hits the front of my ankle.  The Voyageur has a much more comfortable tongue, but sometimes I need a black shoe.)
