1. To stretch the strap, simply hold the strap between your fingers and in small little increments stretch each section of the strap where it feels too tight. You can do the same for the toe pole if this feels too tight.
2. Continue to do this, trying the flip flop on and off, stretching the strap and toe pole until it has reached your desired level of tightness.
3. It is important to note, that while the straps are very elastic, once stretched, the strap will not return to its original tightness, so please be careful not to overdo the stretching!
