This has probably been done but I'd never heard of, or done it.
I took a pair of old footpockets that were kind of hard and were small for Jake. We put them in hot water for a minute or so and he flexed his foot in with a sock on. It was still a little short so I heated it again, he slid his foot in and I stood on his ankle while pulling up on the tendons. Amazing. Perfect fit. And you see the rise in each picket where the bones on his feet are indicating an obvious left and right fin.
Funny because we joke on the boat...."is that the right or left fin"?. But now it's real.I'm really stoked.
I can't believe I never thought of this before. Like a mouthpiece. Shoes are not the same....
Anyone else done this?
