snorkeling fins

Howdy,

I use a pair of atomic fins for scuba, they work fine for me. However,
I was looking at getting some snorkeling fins (full foot) for some
vacation time I am taking where I won't be able to dive.

Now, my problem with full foots in the past has been that they tear my
feet up. The back of my heel or the sides of my foot inevitably have
gotten ulcerated from prolonged full foot fin use in the past.

Is there a brand of full foots that is recognized as being tenderfoot
friendly?
