These sandals are wonderful. I own several different pair from Earth Origins. I usually wear a 10.5 in closed-toed shoes and a 10 in sandals, if the back strap is adjustable.
These shoes are excellent to wear all day and very comfortable and shock-absorbing. Great when you have knee, back and foot issues.
Unfortunately, I had to return these, as the heel strap is not adjustable, pushing the foot a little too far into the foot box in the front. If you are a true 10 they should be fine. If you have sensitive feet you might want to be aware that the braided straps are not underlined and might rub. hence, the four stars.
