Amazing sandals! First buyer. My 12 year old son has serious foot problems - the podiatrist explained that he already had an 8-9 (scale 1-10) on pronation/flat feet. He has a limited selection of supportive sandals as most do not have an arch or textured sole. These are fully compliant. He has constant pain/discomfort in his legs, ankles, knees. He wore them and said it didn't hurt! I liked them so much I ordered a pair! Highly recommended. I like the fully adjustable shoulder straps. I have to admit that at first I didn't understand how they were adjustable and almost thought it was an incompatible size - I watched a video on how to adjust them. Great. 5 Stars. I can't wait to get mine.
