HAPAD Dancer Pads are for "Turf toe", simple sesamoiditis or irritations under the big toe. A perfectly designed pad, given its name from the common use by dancers to relieve calluses and blisters under the big toe. Turf Toe is caused by a hyperextension of the great toe, producing a swollen, painful joint. Given its name from frequent occurrences on artificial surfaces. Sesamoiditis causes localized tenderness and swelling of the tissue at the big toe. Common among dancers, joggers and runners.
