@ Paul, I also have a croc style shoe that is my go to shoe when I'm in camp or crossing water. I made these mainly to see if it would work, and something super light weight for around camp. I may only get one trip out of them, but it's fun just to make new gear and try it out, will see. The one problem I have, is they don't make these any bigger, these are tailored towards women, and I have a size 12 foot that barely fits inside. I would have used 2 pieces of ccf instead of the spa flip flop, but my machine wont sew something that thick.
Thanks for all the comments, Jack
