Are there socks that are better for plantar fasciitis than others? The short answer to that question is no. However, there are products that can be worn under socks that can help with plantar fasciits.
There is product termed Plantar Fasciitis sleeves. Now before I go on, none of these sleeves should be used alone in plantar fasciitis treatments. They should be used in conjuction with stretching, NSAIDS, Night Splints
But, Plantar Fasciitis Sleeves can help. They accomplish this by providing compressing within areas of your foot, which helps stretch the plantar fascia. Remember, Plantar Fasciitis is caused by a tight plantar fascia. The compression sleeve works by stretching out the plantar fascia while you walk or run. This is ideal for an athlete that does not want to miss time, or someone that needs to be on their feet. This sleeve can be worn in conjuction with orthotics, as well.
The other trait provided by the Plantar Fasciitis Sleeve is it provides compression which forces edema and swelling out of the foot. By compressing the edema out of the foot this aids healing as well as reducing pain.
