the strap around the big toe is too loose, but the left is much looser.  The strap that goes across the foor on the left sandal is very loose as the strap is longer than the right.  The left sandal is slightly larger than the right.  I was going to return the sandals, but it cost more to return them than the original price.  I'm not happy with these.  I will have to have the left shoe fixed by a shoe maker which will cost even more money.
