I was going to buy a kit from Tandy when the kits where on sale, but didn't. I got the bits to make a belt instead. I decided to make a custom fit set instead. My feet are kinda Yetti shaped, so custom fit works better. I spent a few evenings over a week or so to get these put together.
I love the Internet. Plans, videos, etc. I've made a single pair, now I can do it without any references.
