I used these for about a year. The wire on the right shoe broke because it got caught on rocks, so I replaced it with a new one. My foot size is 26.5cm, but I chose 3L (27.0-28.0cm) for a more comfortable fit. I wore them for one season and had no problems at all. I do not have athlete's foot or any other foot fungus. I always washed them after use. Please comment if you have any questions.
