I used the battery trackstraps barefoot in the summer. the strap underneath your feet was really annoying at first but I got used to it eventually. They're pretty stable, a little more so with socks in the winter. They do actually last as long or longer than the index controller batteries do.

Compared to the tundra trackers they are still pretty bulky and annoying on your feet, but I got used to it.
