“…Murphy et al [11] tested many kinds of shoes to show the plantar pressure's importance for the research. Otherwise, two test data can be compared and analyzed: pressure distribution comparison, synchronization comparison, impulse comparison, force curve comparison, stability comparison, cerebral palsy pressure distribution comparison, preoperative and postoperative gait comparison; multiple test data can be averaged: pressure average, valgus average; provide personalized correction program [12] [13] [14].…”

The objective of this study was to design and produce highly comfortable shoe products guided by a plantar pressure imaging data-set. Previous studies have focused on the geometric measurement on the size of the plantar, while in this research a plantar pressure optical imaging data-set based classification technology has been developed. In this paper, an improved local binary pattern (LBP) algorithm is used to extract texture-based features and recognize patterns from the data-set. A calculating model of plantar pressure imaging feature area is established subsequently. The data-set is classified by a neural network to guide the generation of various shoe-last surfaces. Firstly, the local binary mode is improved to adapt to the pressure imaging data-set, and the texture-based feature calculation is fully used to accurately generate the feature point set; hereafter, the plantar pressure imaging feature point set is then used to guide the design of last free surface forming. In the presented experiments of plantar imaging, multi-dimensional texture-based features and improved LBP features have been found by a convolution neural network (CNN), and compared with a 21-input-3-output two-layer perceptual neural network. Three feet types are investigated in the experiment, being flatfoot (F) referring to the lack of a normal arch, or arch collapse, Talipes Equinovarus (TE), being the front part of the foot is adduction, calcaneus varus, plantar flexion, or Achilles tendon contracture and Normal (N). This research has achieved an 82% accuracy rate with 10 hidden-layers CNN of rotation invariance LBP (RI-LBP) algorithm using 21 texture-based features by comparing other deep learning methods presented in the literature.

“…Stress fractures in the fifth metatarsal region have a low incidence in soccer, but are considered of concern due to the high rates of relapse and the time required for recovery. 42 Although the relationship between the boots and the incidence of stress fractures is inconclusive, 43 it is suggested that foot pressure overloads may be a risk factor for stress injuries, 19,44,45 mainly in the fifth metatarsal region. 42,43 While Queen et al 28 did not find any differences in pressure distribution between boots with round-shaped studs and boots with blade-shaped studs, Bentley et al 32 found higher pressure peaks at the lateral border of the foot caused by boots with blade-shaped studs.…”

Soccer cleats with blade-shaped studs promote greater traction on the pitch and can be beneficial for soccer performance. On the other hand, movements with rapid changes of direction, associated with the high traction of soccer cleats, can increase overload and risk of injuries. Given the lack of consensus on the effects of these cleats on mechanical overload during specific soccer movements, the aim of this systematic review was to determine the effects of wearing cleats with bladed studs on mechanical overload in soccer. A search was conducted in the PubMed, Scopus, and Web of Science electronic databases between October and November 2017. Non-original articles were excluded, as were those not related to soccer or cleats, and those not written in English. Eight articles were included that tested the effects of bladed studs on overload and that used biomechanical tests. The tasks evaluated were: running in a straight line or with changes of direction, and landing of jumps. The resulting joint torque, soil reaction force, electromyography, and plantar pressure were measured. There was no influence of bladed shaped studs on joint torque or on ground reaction force. There was an increase in plantar pressure on the lateral part of the foot in bladed studs compared to Society cleats and running shoes. When compared with round studs, the results were inconclusive for plantar pressure. Round studs, caused greater electromyographic activity in the quadriceps muscles than bladed studs. It was concluded that wearing bladed-stud cleats does not result in greater mechanical overload during running or landing of jumps. Evidence Level I, Systematic Review.

“…La presión plantar, el centro de presión y otras variables de la dinámica del pie son generalmente evaluadas de forma estática, estas evaluaciones se enfocan en la adaptación en el soporte de peso y equilibrio en el futbolista 12 por lo que se dificulta realizar la correlación con el comportamiento de la dinámica del pie durante la práctica real de fútbol ya que en esta se realiza un soporte unilateral principalmente en el miembro inferior no dominante, soportando el peso corporal y proveyendo estabilidad al atleta [11][12] .…”

Objetivo: Describir el comportamiento de la dinámica plantar durante la ejecución de un circuito de habilidades técnicas específicas del fútbol. Método: Se diseñó un circuito que incluyó habilidades técnicas específicas en el fútbol, se validó y aplicó a 20 jugadores de las selecciones de fútbol de La Universidad de La Sabana, para la medición de la dinámica plantar, se usaron las plantillas electrónicas Open-Go MOTICON. Resultados: La distribución del centro de presión tuvo tendencia hacia anterior y medial en la mayoría de las fases del circuito, el desplazamiento y velocidad del centro de presión fue mayor en el pie derecho con respecto al pie izquierdo en todas las fases, la fuerza de presión ejercida por los pies, fue mayor en el pie izquierdo con respecto al pie derecho. Conclusión: La presión plantar de los participantes tuvo tendencia hacia anterior y medial siendo indicador de la posición en inversión bilateral de los pies, además, la fuerza de presión fue mayor en el pie izquierdo con respecto al pie derecho (p 0.017) durante todas las fases del circuito.
