I prefer VRshoes for foot tracking rather than straps. I found it hard for the straps to stay on while keeping circulation. Can tie the trackers to your shoes using any old elastic or thin bungee.

Other than that, any belt for the hip. I use a 1/4" backpack clip like pic related to offset the tracker from my hip, which helps for occlusion. Otherwise, elastic or bungee to the belt also works.
