Toe stretch
The next three exercises are often done in a progression. Start with the calf-plantar fascia stretch and then move on to the calf chair stretch and the stair stretch. Talk to your health professional about how long you should do each one before moving on to the next one.
Calf-plantar fascia stretch
Chair calf stretch
Talk to your health professional about how long to hold the stretch. A general recommendation is to hold the stretch 20 to 30 seconds and repeat it 3 to 5 times, 2 to 10 times a day.
Stair stretch
This stretch can also be done with your knee slightly bent.
