I have been buying this sandal at a local shoe store for years but it went out of business.  I bought 2 pair through Amazon and other reviewers suggested buying the shoe in a size larger.  I took this suggestion but much to my chagrin found that the larger size was just TOO large.  I wear a size 6 and bought a size 7.  They are too loose and too long.  Love the sandal, but the change in size was a very bad decision.  They cause me to walk unevenly because of the looseness and they make my feet ache.
