I have several pairs of Merrell sandals that are 3 years old. I've worn them almost non-stop in the warmer months and they are finally wearing out. I love them. I have tried multiple times this summer to find some replacements. This will be the second pair I've sent back this summer. They have been too big and too wide. I have a pretty normal width foot and almost always wear an 11. Both pairs were too long and too wide. I don't know if they've altered their sizing or what. Also, the shoes came lose in a large box, not inside a shoebox, almost like the original packaging had ripped open and it was repackaged along the way. Hopping that won't cause an issue with the return.  I have one more pair of Merrells on order right now and will try a size 10. This will be the last chance.
