Description

Shoes for correction of hallux valgus

The present invention relates to a shoe for correcting hallux valgus, and more particularly, it is configured to effectively block the factors that cause hallux valgus and to support only the necessary part of the foot, thereby reducing manufacturing cost and minimizing unnecessary pressure. It relates to a shoe for correcting valgus.

The foot is an organ composed of many bones, ligaments, tendons, and muscles, and plays an important role in maintaining the body's center of gravity, balance, and posture, and absorbing shocks from the ground when walking (Kim, Kim, & Bang, 2011). When the foot is weakened, the balance of the entire body is disturbed, causing abnormal posture and dysfunction, and the shape of the foot can change because it cannot withstand the weight load (Lee & Oh, 2017; Oh, 2012). The pathological condition of the foot can cause musculoskeletal disorders in the lower extremities along with impaired walking (Stolt, Suhonen, Kielo, Katajisto, & Leino-Kilpi, 2017), and lead to decreased blood circulation, which can threaten the general health (Oh, 2012) . Foot health can be viewed as an aspect of overall health rather than simply a foot problem (Stolt, Katajisto, Peltonen, Suhonen, & Leino-Kilpi, 2020).

Nurses work standing up for most of their work hours, constantly moving, supporting or lifting patients, and lifting heavy objects. It was found that nurses worked standing or walking for a total of 6 hours or more during an 8-9 hour work day (Yoon et al., 2018), and walked an average of 6-8 km or more based on 12 hours (Welton, Decker, & Zone-Smith) , 2006). Due to such long standing work, nurses commonly experience leg swelling or foot pain (Choi, 2015; Oh & Yoon, 2008), which can reduce nursing productivity and reduce work performance, which can lower the quality of nursing care. Yes (Lee, Park, Kim, & Jung, 2014). Foot problems may require nurses to seek medical treatment or cause leave or turnover (Stolt, et al, 2017), and may impair quality of life by reducing self-esteem in terms of beauty as a woman (Kim). , Jung, Kang, Song, & Kim, 2003).

As a result of examining the foot health status and foot health-related characteristics of nurses at a university hospital, the diseases with the highest prevalence among nurses were plantar fasciitis and hallux valgus, and it was found that the foot health status of the nurses was not good. In addition, the foot health of the nurses was young, and the more the foot diseased, the more severe the pain and functional impairment.
