These belts are commercial-grade "professional" belts with double natural latex tubes that are more than three times longer.
Colored coatings represent different levels of resistance.
The feet are made of nylon and Velcro.
Each foot strap has a neoprene pad for comfort, so the boot belt can be used barefoot or wearing sneakers.
No height or weight restrictions.
If you are comfortable enough to practice, you should be able to use it.
