Pulling out is not a bad thing. They were probably fitted to "break before your ankle does".
We came away from Santander with a desire to use the windsurf loops. I find the amount of space in the shocks mean that I'm moving before the top of my foot hits the loop and it may explain why they were gettign trashed (stopping a moving thing generates big static loads). That said, the rest of the world loves them and they may well be correct.
We picked up a set of 4 velcro adjustable neoprene board loops from the very nice windsurf shop in Sheppy on Sunday. They were reduced to clear at £15 for the set and will be fitted by tying them in place with elastic and then taping over the elastic to stop it all rotating.
