Various shoes are worn by distance runners throughout a training season. This study measured the differences in ground reaction forces between running shoes, racing flats, and distance spikes in order to provide information about the potential effects of footwear on injury risk in highly competitive runners. Ten male and ten female intercollegiate distance runners ran across a force plate at 6....

Introduction: High heel shoes affect the knee joint and can cause arthritis in the tibiofemoral (TFJ) and patellofemoral joints (PFJ). There is a dearth of research investigating the contact forces of TFJ and PFJ. Therefore, the purpose of this study was to assess the effect of high heel shoes on muscle forces as well as TFJ, and PFJ contact forces during walking.   Materials & Methods: A tot...

The perceived differences between comfortable and uncomfortable shoes and the fit preferences in the different regions of ladies’ shoes were explored. Twenty Hong Kong Chinese females participated in the study. Each participant wore and rated the different aspects of their own comfortable and uncomfortable shoes. The Wilcoxon signed rank tests showed significant differences in ten perceived cha...

Background Patients undergoing forefoot surgery often require specific footwear to relieve the operated area. Post-operative footwear can be very different in relation to the amount of weight born by the forefoot [1,2]. While these special shoes are intended to be worn for short periods following surgery, a compromise must be found between level of comfort and functionality. In this study the i...

Special Note: Chain retailers are very conscious of the need to carry only private-label models/styles that are easy and less expensive to produce so they can sell their private-label shoes at attractively lower prices than name brand athletic footwear. As a consequence of their efforts to order only models/styles that are simpler to produce, production run set-up costs for private-label pairs ...

OBJECTIVE To study the influence of prolonged wearing of unstable shoes on standing postural control in prolonged standing workers. METHODS The participants were divided into two groups: one wore unstable shoes while the other wore conventional shoes for 8weeks. Stabilometry parameters related to centre of pressure (CoP), rambling (RM) and trembling (TR) as well as the total agonist/antagonis...

The aim of this research was to examine the effects of high-top shoes and low-top shoes on sagittal ankle ROM, kinetics and power output during single-leg and double-leg jumps. Twelve male subjects were requested to wear high-top and low-top shoes to perform single-leg and double-leg jumps. Ankle joint kinematics and kinetics data were collected using Vicon system and force plates. Shoe collar ...

Objective(s): The effect of silica nanoparticles (SNPs) in sport shoes outsoles on the  parameters related to anterior cruciate ligament (ACL) Injury has not been investigated. The aim of this study was to investigate the effect of shoes outsole containing a composite of thermoplastic elastomer based on styrene-butadiene and silica nanoparticles (TPEN shoe) on Knee Valgus Angle (KVA) as a risk ...
