The influence of shoe sole's varying thickness on lower limb muscle activity

Do thicker midsoles increase shock attenuation and do thin midsoles facilitate propulsion during lunge maneuvers? Footwear design for racket-sport industry

“…However, pronation must end before takeoff to enable the foot to become more rigid [30]. Neither, our findings on rearfoot frontal kinematics did not correspond with the hypothesis made according to previous studies, who reported that wearing a shoe with a thick midsole causes the foot position to be high relative to the support surface, thereby creating an unstable position [28]. The causal relationship between the magnitude of external torque and its effect on rearfoot motion was not observed under the thick midsole condition in our study.…”

“…Decreased proprioceptive feedback from the sole of the foot and impaired foot positional awareness and stability might cause excessive midfoot pronation. A physiological mechanism known as the oscillatory phenomenon might cause muscular afferent discharge following intense extrafusal stimulation, which could interfere with the accuracy of information regarding the plantar-surface position and orientation and eliminate proprioceptive input from plantar mechanoreceptors [26][27][28]. The degradation of foot-position awareness, namely the postcontraction sensory discharge or aftereffects caused by intense muscular activity used to stabilize the thicker plantar surface of the foot [28], might result in underestimation of the joint position.…”

In addition, greater pronated at the midtarsal joint is not a possible reason to compensate for thicker-midsole shoes in terms of shock absorption because thicker midsoles have a greater capacity for force attenuation as indicated by material testing.…”

Barefoot vs common footwear: A systematic review of the kinematic, kinetic and muscle activity differences during walking

“…A common feature of modern athletic footwear is that of increased sole thickness which is marketed as providing cushioning against harmful impacts. Recent research has demonstrated that wearing this type footwear evokes significantly increased activation in the Peroneus Longus suggesting greater interference to ankle stability [11]. Moreover, footwear has been shown to hinder the kinesthesia [12], with greater awareness of foot position observed in volunteers standing barefoot compared with wearing athletic footwear.…”

Comparison of Biomechanical Factors on Badminton shoes between Anti-slip outsole and Non anti-slip outsole

“…신발 특성 중 신발 뒷굽의 차이(지렛대 모양의 쿠션을 가진 보행화와 U자 모양의 밑창을 가진 보행화)는 보행자의 보행특성 변화(관절의 가동범위와 궤적, 관절모멘트와 지면반발력)에 영향을 미치며 [3], 오일저항 아웃솔은 오일 비저항 아웃솔보다 적당한 미 끄럼 저항을 가지므로 전문 작업화의 아웃솔은 반드시 오일저항(oil-resistant)을 가져야 한다 [6]. 그리고 달리 는 동안 아웃솔의 재질특성이 근육 활성화와 에너지 양상에 영향을 미치며, 아웃솔의 두께가 증가할수록 발 목 외측인대 상해위험이 증가한다 [7,8]. 또한, 소방화(4 종)와 안전화(1종)의 아웃솔 상태(마모된 상태, 마모되 지 않은 상태)에 따른 미끄럼 저항(slip resistance)을 평가하면서 아웃솔의 중요성을 지적하였다 [9].…”
