Those are cool. My daughter would like them because her running shoes are too big for the toe cage. I would like them too because then I could wear my running shoes which are more comfortable for walking than the smaller pair that fits in my toe cage.

I do a sort of "half cage" but it's not quite the same thing. I have one toe cage, it's on the right side. I discovered that I hate the left one because by the time my foot's in, it's time to come out again. But the right foot is always in, whether I'm moving or stopped. So I took the left one off! It looks funny but it works for me!
