“…The participants were instructed to walk on a treadmill with each of three slopes, a 9 degree incline (uphill walking), a -9 degree decline (downhill walking), and a level surface (level walking) [26,27] at 0.75 m/s (2.7 km/h) speed for all slopes [26][27][28]. Uphill and downhill walking were performed on different days, since walking on uphill and downhill slopes should be performed on separate days with a lapse of 24 hours to avoid interference of concentric (uphill walking) and eccentric (downhill walking) contraction [29].…”

Background Pes planus (flatfoot) is a common deformity characterized by the midfoot arch collapses during walking. As the midfoot is responsible for shock absorption, persons with flatfoot experience increased risk of injuries such as thumb valgus, tendinitis, plantar fasciitis, metatarsal pain, knee pain, lower-back pain with prolonged uphill, downhill, and level walking, depriving them of the physical and mental health benefits of walking as an exercise. Methods Fifteen female college students with flatfoot were recruited. A wireless plantar-pressure system was used to measure the stance time, cadence, plantar pressure, and contact area. Parameters were compared between wearing flat and arch-support insoles using a two-way repeated measures ANOVA with on an incline, decline, and level surface, respectively. The significance level α was set to 0.05. The effect size (ES) was calculated as a measure of the practical relevance of the significance using Cohen’s d . Results On the level surface, the stance time in the arch-support insole was significantly shorter than in the flat insole ( p <0.05; ES = 0.48). The peak pressure of the big toe in the arch-support insole was significantly greater than in the flat insole on the uphill ( p <0.05; ES = 0.53) and level surfaces ( p <0.05; ES = 0.71). The peak pressure of the metatarsals 2–4 and the contact area of the midfoot in the arch-support insole were significantly greater than in the flat insole on all surfaces (all p < 0.05). Conclusions These results imply that wearing an arch-support insole provides benefits in the shortened stance time and generation of propulsion force to the big toe while walking on uphill and level surfaces and to the metatarsals 2–4 while walking on the level surface. More evenly distributed contact areas across the midfoot may help absorb shock during uphill, downhill and level walking.

“…The materials used for manufacturing orthotic insole may also be effective on flat feet function. Huang used hard arch supports walking uphill with the orthotic insole, i.e., harder, compared to walking without insoles or downhill walking [22]. Hard thermoplastic insole significantly improved flat feet function in this study; however, the mean score failed to reach 100.…”

“…For example, Banwel and Yurt assessed flat feet function after using orthotic insoles for a while [20,21]. Walking uphill was also harder for flat feet individuals using arch supports in Huang's study [22]. Kirby claimed that the medial heel skive technique is useful to control pronated feet [23].…”

Objectives: Flexible Flat Foot (FFF), a common foot deformity decreasing medial longitudinal arch height is often comorbid with subtalar joint pronation causing physical activity difficulties in this population. Among the orthotic insoles prescribed for improving foot function, foot orthoses with medial heel skive technique have a limited research background. The present study aimed to investigate the effects of the custom-mold insole with medial heel skive technique on physical function in FFF. Methods: Eighteen adults with FFF from the University of Social Welfare and Rehabilitation Sciences students and staff participated in this study. Custom-Mold insole with medial heel skive was fabricated for all research participants. Physical function in the activities of daily living and sports was assessed by the Foot and Ankle Ability Measure (FAAM), Activities of Daily Living (ADL) subscale (ADL-FAAM), and SPORT-FAAM questionnaires at the beginning of the study and 6 weeks after. Paired Samples t-test and nonparametric tests were used to compare the collected results. Results: After 6 weeks of using the insole with medial heel skive technique, scores in both ADL and SPORTS activities were significantly improved. Discussion: Foot function improvement was not found in all of the studies assessing foot function in flat feet after using different orthotic insoles, by different questionnaires or other systems. In this study, foot and ankle function was significantly improved per FAAM questionnaire- which had highly limited use in orthotic interventions in flat feet population- using medial heel skive technique; however, further studies are required to accentuate medial heel skive technique effect on flat feet function by comparing this technique with other positive cast modifications to control the flat foot. According to the present study results, custom-mold insole with medial heel skive may improve physical function in FFF and can be prescribed in this group.

“…Knowing that SSCO were designed to provide additional arch support and if we hypothesize that a flattening of the arch is associated with fatigue (i.e. loss of muscle integrity over time), this result could potentially be linked to the findings of, see [17], who reported that insoles with custom arch support help reduce the impact of fatigue during up-and downhill walking. However, none of the results presented in the current study reached statistical significance.…”

“…tibialis anterior, gastrocnemius medialis, rectus femoris and biceps femoris) decreased after wearing the custom-made orthotics. Also, see [17], studied the impact of insoles with custom arch support during uphill and downhill walking for individuals with flatfoot conditions. Their findings showed that added arch support led to a significant decrease in peak oxygen uptake (VO 2 ), as well as a potential reduction in the activity of the rectus femoris.…”

Customized insoles are commonly prescribed to prevent or treat a variety of foot pathologies and to reduce foot and lower limb fatigue. Due to the patient-specific design and production of such orthotics, the concept of self-selected customized orthotics (SSCO) has recently been developed. The goal of this study was to assess the impact of SSCO technology on several physiological and biomechanical variables during uphill power walking. Thirty male participants underwent an uphill power walking intervention at constant speed in two insoles conditions (control and SSCO). The electromyographic (EMG) activity of their right gastrocnemii and vastii muscles was measured. Perceived fatigue was assessed every 5 minutes and the intervention stopped when the targeted fatigue level was reached. Baseline and post-intervention assessments were also performed. Sixty-three percent of the participants experienced an improvement in foot fatigue while wearing the SSCO. The foot arch seemed to collapse less when participants wore the SSCO, but statistical significance was not reached. The changes in mean EMG activity was not consistent between the 50% isometric contraction and the walking trial. In conclusion, while some interesting trends were observed when wearing SSCO, further investigations should be performed to try and reach statistical significance.
