I get cold on my feet with 6mm Mares socks in the winter, so I doubt 3mm will do.
Besides ,this Mono is a 1:1 fit.. I will not be able to use 3mm sock here.. but thanx for your input
Edit: on the other hand,this fin is "closed around the toes" so maby it will feel warmer than my bifins(omer), but still.. it wont fitt with 3mm socks..
