- I am wondering, why dont people use neoprene vibram 5 fingers? (i tried non neoprene version, they are ok, but killed my calves on the run)

- How do you prevent the cord from wrapping around you or partners arm during the swim? (my partner swim 15s faster per 100, cord wrapped my arm and I couldnt use it at all , we had to cut it mid swim)

- instead of compression socks, why not cut lower leg portion of a full wet suit as sleaves for calves?
