i Always sup in booties. yep not the best look... but
most places i sup are over shallow reef, nothing worse than jumping off your board in 1ft of water straight on to jagged reef
comfort factor increase
get nose rides on the JL, without having to cover the front end in wax.
i use the split toe, ankle, o'neils.,, the only hiderance is the exta 40 seconds it takes to put them on , when your itching to get in the surf.
