Toss in the wash with cold water. Air dry. Boom.
Size is different
"I love Rothys and have been wearing them for years, but this new Point III does not fit the same. I used to do a half size up and they were a perfect fit, never rubbed my heels. These fit bigger. I tried the half size up and they blistered my heels. So I tried my normal size, and they still are loose in the heels. Please bring back the sizing of the old style! Otherwise, the shoes look great and have the same durability."
