I bought my Chaco z/1's about 2 months ago and have worn them fairly consistently. The problem I have is around my toes. I adjust the straps around my pinky and big toes every time I put them on so that they aren't too tight. After just a short period of time, the straps begin to rub on my pinky toes and the my big toes to the point of being completely raw. The straps around the toes seem to tighten as I walk. I want to know if the sandals I have are too small or too big. If I need to man up and continue wearing them in or what. Any responses would help.
