I was going to put this in off topic, but as it's football-related, I've put it here, on the hope of getting more replies. Feel free to move, though.
I've got a pair of boots, which, at some point over the last season, have lost 2 threads into which the studs go. As they're pretty decent boots, although they're about 10 years old, I don't want to replace them (they're my 6-studs for rugby, and I only use them for about 3 games per season, plus Sevens tournaments). Can I get new threads put in to the cavities, and if so, should I take them to a cobbler or to a sports shop? Also, how much would it cost?
