The calf strap is most popular with athletes wanting to increase flexibility in their calf and hamstring. It allows for more control in different positions such as lifting the leg for a great hamstring stretch. Due to the different sizes of peoples calves this strap is custom to your calf, see measurement guide.
The stretch provided is even more effective than having another person push the leg up for the individual getting the stretch.
