Lacrosse has changed their sizes up in recent years for those of you that havent bought any in a while. I have 3 pairs in 13 that I've worn for years. My wife bought me two new pairs of 13s for Xmas because a couple pairs are starting to crack. Neither pair fit, too small, so I had to return them. Ended up swaping them out for Readheads as those were the only ones at BPS that fit.
