The purposes of the present study were to introduce the shoe we developed for metatarsus primus varus (MPV) correction, and confirm the significance of this development by examining the relationship between the hallux valgus (HV) and MPV angles. The shoe has a structure, where a push-up metatarsal pad is elevated to correct MPV when the body weight is applied to the forefoot during gait. X-ray photography to measure the HV and first-second metatarsal (M1-M2) angles in 11 females (mean age:67.8±13.9 years) with HV revealed a significant positive correlation between the 2 angles (r=0.861,R2 =0.741). Based on this, it may be necessary to examine the effectiveness of wearing the shoes for a given period to reduce pain and improve gait in those with HV, as well as to prevent and improve the deformity itself.
