AnotationBarefoot footwear is currently becoming very popular (Esculier et al., 2015). So far, it is well known that footwear companies using barefoot technology try to simulate walking barefoot in an effort to support all 104 skin mechanoreceptors (Kennedy & Inglis, 2002). Compared to normal footwear, this type of footwear is very flexible, has a minimal sole, neutral drop between the heel and toe, low weight, minimal damping of tread, absence of foot movement support and stability (Sinclair et al., 2013; Xu et al., 2017). According to previous studies of walking in different types of footwear, it is still unclear whether adults are able to adapt to current barefoot trend available in the market (Gu et al., 2014; Khoury et al., 2015). Current studies show both positive and negative effects on the human body when wearing barefoot shoes. Daily use of shoes with a minimalist sole has been shown to positively affect at musculoskeletal structure of the foot, improving balance and walking efficiency (Cudejko et al., 2020; Petersen et al., 2020; Ridge et al., 2019). The authors of the studies (Trombini-Souza et al., 2015) point out that walking in barefoot shoes reduces the adductive moment of the knee joint and improves the activity of torso muscles measured on women with osteoarthritis (Lisón et al., 2016). In contrast, a study (Sacco et al., 2012; Willy & Davis, 2014) has the negative impact of walking in barefoot footwear where are greater vertical forces acting on the ankle and knee joint compared to walking barefoot or in neutral running shoes. Because knee cartilage responds to cyclic loading during routine activities such as walking (Chaudhari et al., 2008) it is necessary to demonstrate the effect of footwear on the condition of knee cartilage.
