A patch (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) of low friction materials, such as a film of polytetrafluoroethylene (12, 28, 38, 52, 53, 60, 72, 86) is sized to provide an area of low friction support for a portion of a human body (80) relative to an object such as a shoe (82) or prosthetic socket (124, 142). The patch (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) can be lined with foam (30, 42, 56), or preferably, a stretch fabric (14, 40, 70) so that it will fit around irregular contours of the shoe (82), or socket (124, 142), or the skin itself. The patches (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) reduce shear trauma in critical load areas. After identifying regions of high loads, the method comprises applying the patches (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) as needed to avoid sores, calluses, blisters and abrasions.

Une pièce (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) en matériaux à faible frottement, tels qu'une film de polytétrafluoroéthylène (12, 28, 38, 52, 53, 60, 72, 86) est dimensionnée de sorte qu'elle constitue une zone de faible frottement pour une partie du corps humain (80) par rapport à un objet, tel qu'une chaussure (82) ou une chaussette prothétique (124, 142). La pièce (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) peut être doublée de mousse (30, 42, 56), ou de préférence, de tissu extensible (14, 40, 70), de sorte qu'elle s'adapte aux contours irréguliers de la chaussure (82), ou de la chaussette (124, 142) ou de la peau elle-même. Les pièces (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) réduisent le traumatisme de cisaillement dans des zones de charge sensibles. Une fois les régions supportant des charges élevées identifiée, ledit procédé consiste à appliquer lesdites pièces (26, 36, 50, 66, 86, 88, 94, 100, 114, 120, 120A, 122, 126, 128, 130, 132, 150, 152) selon les besoins, de sorte que les lésions cutanées, les callosités, les ampoules et les érosions soient empêchées.
