i saw a guy wearing a pair a few months, and quite honestly they gave me a start, as when you look at them, its like wearing gloves but on your feet, truly horrible.
I'm thinking that if they made a fur lined boot then this could be warmer then "Normal" boots as each individual toe has it's own housing so maybe good for winter?
don't do it, if someone treads on your foot, even by accident, likely to break all your toes. Just like goal keeper gloves, i did tell a relative about them months ago, but couldn't explain properly, now i have a picture will have to pass that along.
