I never wore sandals in my life until 3 years ago when I bought my 1st pair of Tevas - the same style as these. I wore them almost every summer day. I wear size 11 1/2 Wide shoes. The 1st pair, size 12 were a little long but comfortable. This time I bought the size 11 1/2 and although they're not broken in they fit well, feel comfortable with good arch support and feel familiar.
