A common characteristic of Plantar Fasciitis is that the plantar fascia tightens up overnight, which is often the reason pain is worse in the morning then lessens as the structure warms and loosens up.
The Plantar Fasciitis Night Splint is worn over night to help prevent the plantar fascia from tightening up. It provides a gradual resistance to tightening rather than trying to stretch the fascia in a short space of time.
Some people prefer to start wearing it for an hour or two to start with and gradual build up length of time wearing it as comfort allows. Often by the time it can be worn all night the injury is gone.
A plantar fasciitis night splint can be one of the most effective product for helping to treat plantar fasciitis heel pain.
