I recently upgraded to Deep6 Eddy fins. With my current 2mm neoprene booties, there's some slop in the fit that I don't particularly like. My bootie moves side to side, but the length and spring tension fit well. I think this would be easily remedied with a chunkier boot, but I'm not sure where to begin my search. I'd appreciate any recommendations for a higher volume boot suitable for warm water wetsuit diving.
