OK, I found the deal of the year at Leisure Pro. They have a pair of spring straps for $9.95 usd

I have seen similar straps for $65 at my LDS. I thought I would let you all know about this STEAL!! Anyway here is a link to them:

Anyway, I bought a few pair and tried them out today. I have to say they are amazing. So easy to use, very secure and comfortable. I highly reccomend them! Oh yea no more broken fin straps to deal with right before you are ready to splash!!!!!!!!!!!!!!!!!!
