I've only done it a couple times, and unfortunately tonight was one of them. I was being a little sloppy on a turrn and my heels smacked the top of the gutter. Nothing broken but I'll probably have a good bruise. Add this to lanelines (the plastic floats can be sharp when broken) and hand collisions with other swimmers to the list of hazards.
Not recently with the heels, but I have recently tangled my fingers in the lane line while swimming backstroke. Thankfully nothing broke, but my hand was sore for weeks. Bashing my wrist against a concrete wall while swimming butterfly in an outside lane resulted in another hand injury that took weeks to heal. Somehow I managed to do that to both hands this fall.
Swimming straight would probably help!
