Summary: This study assessed the behavior of the center of pressure (COP) and its relationship with impact severity during heel-toe running in athletic footwear. The study found that the location of the COP at foot strike is associated with the vertical loading rate and peak tibial accelerations. A more anterior foot strike was associated with higher peak tibial accelerations and greater impact severity.

Summary: This study investigated the influence of midfoot stiffness of running shoes on foot segment kinematics and ground reaction force during heel-toe running. The results showed that shoes with high midfoot stiffness reduced the range of motion between the forefoot and rearfoot, as well as between the forefoot and midfoot in the frontal plane. However, no differences were found in the ground reaction force characteristics among the different shoe conditions.

Summary: The heel-to-toe drop of running shoes significantly influences running patterns and lower extremity joint loading. Running shoes with large drops may be disadvantageous for runners with knee weakness but advantageous for runners with ankle weakness.

Summary: This study found that the condition of footwear, foot-strike pattern, and step frequency affect the spatiotemporal parameters and lower-body stiffness during running. Barefoot running showed higher stiffness compared to shod running for both foot-strike patterns, with stiffness increasing as step frequency increased.

Summary: This study aimed to investigate the acute effect of heel-to-toe drop (HTD) and running speed on lower limb biomechanics and strike pattern in recreational runners. The results showed that shoes with -8 mm HTD significantly increased strike index and vertical instantaneous loading rate. The range of motion of metatarsophalangeal, ankle, and knee joints also significantly changed.

Summary: The objective of this study is to investigate the probability of successful transition from running in traditional shoes to barefoot. The study found that most runners are able to successfully transition to barefoot running, but using a 20-week transition period and an intermediary minimalist shoe may result in some individuals failing to transition.

Summary: A study found that embedding a carbon-fiber plate into running shoes can improve running economy, but its effects on foot mechanics are poorly understood. This study used computational simulations to explore how changes in carbon-fiber plate thickness and location can affect plantar pressure, strain, and metatarsal stress. The results showed that thicker carbon-fiber plates reduced peak plantar pressure and compressive strain under the forefoot, with the lowest-loaded conditions being the most effective. However, the effects on metatarsal stress varied depending on the plate's location.

Summary: Footwear may moderate the asymmetry in lower limb loading during peak growth in adolescence. This study compared the effects of barefoot and shod running on vertical ground reaction force and loading rates in adolescents. The use of conventional running shoes resulted in lower loading rates but higher asymmetry compared to running barefoot or wearing partial-minimal shoes. These findings have implications for performance, musculoskeletal development, and injury in adolescents.

Summary: In addition to aesthetics and comfort, the thermal characteristics of shoes are important. This study proposed a Phase Change Material (PCM)-enhanced shoe sole design to prevent excessive foot temperature rise during daily activities. The design includes a structured porous layer filled with PCM, and paraffin wax (RT35) and PEG 900 were found to show excellent performance. Experimental results showed that these PCM-enhanced shoe soles can keep the foot sole cool during different activities.

Summary: This study aimed to investigate whether fatigue modifies the effect of custom foot orthoses made from EVA and TPU materials compared to standardized footwear on running mechanics, running economy, and perceived comfort. The results showed that acute intense fatigue does not change the effect of custom foot orthoses with different resilience characteristics on running mechanics, running economy, and perceived comfort.

Summary: The study found that compared to rearfoot strike (RFS), forefoot strike (FFS) results in lower impact force magnitude and loading rate, decreased ankle stiffness, reduced knee extension moment, eccentric power, negative work, and patellofemoral joint stress. However, FFS increases ankle plantarflexion moment, eccentric power, negative work, and axial contact force compared to RFS.

Summary: This paper describes and runs a three-dimensional finite element model of a uniformly loaded, single rubber block under loading conditions replicative of a standard slip resistant footwear test. The model considers rubber hyperelastic and viscoelastic material properties, and evaluates its performance through analytical compression analysis and experimental contact area testing. The study also investigates the effect of tread grooves on slip-resistance during walking, analyzing sliding contact areas, contact pressure, stress, and front edge mechanics of the tread model.

Summary: This study investigates the viability of measuring foot inversion angles at initial foot strike from the front view as an alternative to using the back view in 2D video analysis. Results show a significant positive correlation between front and back camera views, and a linear regression equation was derived to convert front-view measurements to back-view measurements.
