Query: Great for new boots

My husband uses these to break in new hiking boots. This is his 3rd set, so they must work well. You can use either on either ankle so if you only have problems with one ankle, you get two. They don't overheat your ankle or foot and you can hand wash and hang dry them. They go up the ankle less than a crew sock and cover about 1/2 of your foot for my husband's size 9.5 foot. My husband swears by them as he goes through 3 sets of boots a year.
