But this sounds like a good idea...you can also use athletic tape for taping stuff up...one of my dive buddies tapes part of his feet before every dive because his fins rub something the wrong way.chickdiver once bubbled...
Quite possibly it is the seam. I have that problem. Scootereing is no problem, but swimming that damn seam dimple smashes down on my second toe, right at the cuticle, and forms a painful raw spot/ blister. Been doing it for 5 years now, i just use a little duct tape on the area in question pre dive.
