DO NOT WATERSTART !
Beginers at wind foil shouldn't not even think about it. I still avoid waterstart, and it require to have thought about it : do not paddle but gently feel for your foil with your front foot, either step on the fuse or push the mast with front foot to control the board.
Beginers should NOT waterstart.
That advice might be a little restrictive, but (very) generally for a beginner if you're waterstarting, the sail is probably too big for the conditions (assuming a floaty board and a high lift freefoil).
Having said that, I wear Ripcurl 3mm Flashbomb booties, which are flexible and generally warm enough for Tasmanian conditions. Split toe, and soft/ thin soles feel pretty natural, but I wear out a pair in less than a year. About $100 a pair well worth it.
