I have big flat feet so I use orthotics but can't wear them. So they bunch up a bit when I tighten them (no arches). Otherwise I really like these shoes. Lightweight, easy to put on and take off, runs well and provides enough protection for the soles of your feet so you don't hurt yourself or feel every rock or pebble. Use them at the beach and camping by the river when I know I'm in and out of the water. would recommend.
