The purpose of our study was to determine if altering the insoles within footwear or walking barefoot, as an attempt to increase or decrease cutaneous stimuli, would improve dynamic balance during a hill-walking task. We hypothesize that compared with foam insoles or iced bare feet, textured insoles or bare feet will result in greater speeds, longer step lengths, narrower step width, shorter stance time, and less tibialis anterior (TA), soleus (SOL), and lateral gastrocnemius (LG) activity during key gait cycle phases. Ten, healthy college students, 5 men and 5 women, completed the protocol that consisted of level walking and downhill transition walking in five different footwear insole or barefoot conditions. During level walking, conditions with the hypothesized greater cutaneous stimuli resulted in greater step length, which relates to a more stable gait. In detail, the texture insole condition average step length was 3% longer than the regular insole condition, which was 5% longer than the ice condition (p < .01). The same signals of increased stability were evident during the more challenging downhill transition stride. Step length during the barefoot condition was 8% longer than the ice condition (p < .05) and step width during the regular footwear condition was 5% narrower than the foam condition (p = .05). To add, during the preswing phase of level walking, TA activity of the textured insole condition was 30% less than the foam insole. Although our data show that footwear conditions alter gait patterns and lower leg muscle activity during walking, there is not enough evidence to support the hypothesis that textured insoles will improve dynamic balance as compared with other footwear types.

ground. 4 These braking and propulsive impulses are required to decelerate and reaccelerate the body toward the new direction and are transmitted via the footwear to the ground. Thus, it is imperative for the player that his unique piece of equipment, that is, his soccer boots, supports him in executing

Discrepancies between the motion of the foot and the shoe have been reported, 13 – 15 and as such, the findings of studies using shoe-based markers should

risk of tripping is increased by wearing footwear without a form of fixation, such as laces ( Sherrington & Menz, 2003 ). It was also found that toe clearance in healthy older women is lower when walking in slippers compared with walking in shoes ( Lo et al., 2017 ). However, 20%–40% of older adults

Footwear is the primary interface between the worker and the work environment and plays a critical role in worker safety. 1 Safety toe footwear is often used to protect workers from the hazards typically encountered in work environments, such as mining, and is thereby required personal protective

preserve RE has not been investigated. Therefore, the primary aim of this study was to determine the instantaneous effects of 2 different designs of foot orthoses: (1) “flexible-arched” orthoses with reduced arch thickness and (2) standard thickness orthoses, on RE compared with footwear only in

Different types of footwear (eg, cleats, athletic shoes, minimalist shoes, barefoot) have also been demonstrated to affect balance. 16 , 19 – 22 For example, wearing athletic shoes has consistently resulted in better performance on the full version of the BESS, as demonstrated by committing

previous studies have shown that footwear and cadence modifications can effectively reduce surrogates of knee joint loading in younger runners. Running footwear ranges from minimalist to maximalist, 12 and is known to affect forces applied at different body parts. 13 Specifically, footwear characterized
