"Footbag can be pretty frustrating when it's supposed to be fun. I was partly driven by this forum - practice, practice, practice... As that is true, I think someone can be too focused on progressing and training that they miss the fun aspect of it." - Bander87
If they have anything remotely like a hole where the inside is, then that really sucks for stalling on the inside.
I'm currently using shoes sort of like these because I don't have better shoes. They tend to be inflexible. I would assume that they would be annoying to mod with all the bright patterns and rubber and whatnot. Being so shiny, they don't look too a either.
Having shoes like these is probably the reason I've only landed a good clipper like 10 times in the last 2 weeks.
