Abstract
Objective. Running barefoot or minimalist footwear is a new trend that is intended to prevent injuries in runners. It is believed that the footwear increases the number of injuries to heel counter favors regarding forefoot. Our goal is to know if this is true or if biomechanics and psychomotor key corridor itself in varying forefoot support. Material and method. 12 runners were selected neutral and with no injuries to which they are recorded each foot 3 supports walking and running in shoes and barefoot mode by digital pressure Podoprint platform, which amounted to 60% travel (27m). The two variables and contrasts were compared in the pressure and surface. Results. Going footwear as to produce pressure changes and in the forefoot area, the surface pressure increases but decreases. Regardless of footwear smudging or barefoot always most forefoot support and the support is greater in the forefoot to rearfoot barefoot footwear. Conclusions. Biomechanics is responsible for more or less support in the race forefoot, the shoe does not condition the support of any region of the foot but if you modify the surface of forefoot pressure.

Summary
El ser humano parece estar especializado para realizar carreras de resistencia por la anatomía y fisiología que presenta en comparación con otros grandes simios. Incluso en superficies duras las fuerzas de reacción que se generan en el antepié en corredores descalzos son menores que las fuerzas que se generan en el talón en corredores calzados debido a que el mayor cumplimiento de tobillo y la flexión plantar del pie en el momento del impacto, ya que estas adaptaciones disminuyen la masa efectiva del cuerpo que choca contra la suelo[5]. Se adapta a la dureza de la superficie manteniéndose rígida, de manera que actúa como un soporte lineal tanto en la carrera como en el salto[14] Esto justifica como el pie se enfrentaba al impacto del choque antes de la invención de la zapatilla moderna y además sugiere que este mecanismo de apoyo de antepié o mediopié en corredores descalzos podía estar protegiendo los pies y las extremidades inferiores de algunas lesiones que hoy por hoy están experimentando un alto porcentaje de corredores. El propósito de este estudio es demostrar que la recepción del impacto contra el suelo en la carrera depende de la biomecánica y forma de correr inherente del corredor teniendo en cuenta como se puede modificar el impacto en función de si el corredor corre calzado o descalzo
