Ive seen the ones that CJL has got, and quite frankly they are the gucci windsurfer velcro ones that can be shortened so short that they go flat on the deck, and lengthened to get my size 12 boots into.
The other option being the Avon ones, that are made out of rubber and where easy to get your feet into, are a potential deck-annoyance.
We had a discussion on another thread a couple of weeks ago about the use of toe-straps and i think the concensus was, that given the sort of airtime we get and the general bouncing around we do, it would be a much safer option to have them, rather than not.
Having been in the Ribtec without them, and having had a few interesting landings in the past month, i think it is probobly better to keep your feet in line with your body. Without them i think there is a tendacy to spread your feet across to the sides of the boat. I think that if you had an unhappy landing this is may cause your back and hips to twist more and take more of a weight bearing, resulting in back injury.
When i have landed sideways in a boat, with feet in the toe straps, i have rolled with the rib, rather than trying to stay upright, or falling down between the tube and the console, which is not generally desirable. I think that trying to keep your body straight is the main thing.
The risk of ankle injury is of course still a factor, but providing you have adequate footwear and your feet well into the straps, i dont see it as risky as skiing.
Having said all of that, and having repeated to CJL the other day, toe straps are as far as i would go, the day that four-point harnesses come into play and bucket seats i think i will be taking things a little too seriously, mind you, i bet its going to happen..........
