What size is best for a men's size 9 foot/shoe?
KEN K Good question
If you wear a size 9 get a size 9 but they probably come in Sm,Med,Lg. and so on I would recomend getting a pair of booty's in a size 9 and the fins in a Lg, or XLG the fin doesn't have to fit exact if you have the neo boots and this will prevent blisters and be far more comfortable and last far longer OK
Hope this helped
