Hi every one, I'm going to be getting my first pair of long fins. I wear a size 43 footpocket with bear feet (Mares Volo Race for warm water scuba), my question is what is the norm when wearing neoprene socks? 3mm sock how much larger for the footpocket or 5mm neoprene sock how much bigger for the footpocket. I'm diving in cold water and 3mm socks are good for the summer but winter will need at least 5mm I'm sure and I would like to, at least for now be able to use the same fins year round. Any suggestions or advice would be greatly appreciated.
