I think Cybershoes work better than these.
Having said that, I’ve gotten a lot of enjoyment from using them to walk across the world in Skyrim VR. The movement required (rolling your feet back towards you) is different to walking but feels convincing enough when you’re in the game.
Cybershoes are just a kind of controller for your feet you use while seated. Less risk of injury and no speed limit, maybe the game but not the player.
