Hi guys, I'm looking for some sizing advice on a pair of Bio-Pro C's. My normal shoe size is a 10.5 or an 11, and that's the crossover point for the large to XL/LL size. I'm hoping to be able to use the fins with both my 3mm relatively thin sole warm water boots, and dry suit boots as well. Do you think the Large is the way to go, or should I think about going XL? I know this has been asked before, but in searching the archives I didn't quite find the answer I was looking for. I know the Bio's strap lengths have changed as well and thought that might affect the answer. Side question - how long do the white fins stay white? Thanks!
