Friction blisters on the feet commonly occur when individuals engage in active pursuits such as running, hiking, and military training. The high prevalence of blisters in active individuals underscores the fact that the pathomechanics of this condition are not fully understood. The traditional blister causation paradigm revolves around heat, moisture, and friction. In reality, foot friction blisters are caused by repetitive shear deformation. The 3 fundamental elements of blister-inducing shear deformation are (1) motion of bone, (2) high friction force, and (3) repetition of the resulting shear events. Rubbing at the skin surface is not a mechanism for friction blister formation. To that end, prevention of the friction blister continues to be an elusive quest for both the patient and the treating clinician. In this article, we aimed to highlight the limitations of the long-held blister-causation paradigm and offer a new explanation.
足部摩擦水疱通常发生在人们进行跑步、徒步旅行和军事训练等活动时。活跃人群中水疱的高患病率表明，这种情况的发病机制尚未完全了解。传统的水疱成因模式围绕着热、湿和摩擦。实际上，足部摩擦水疱是由反复的剪切变形引起的。导致水疱的剪切变形的 3 个基本要素是（1）骨骼运动，（2）高摩擦力，以及（3）反复发生的剪切事件。皮肤表面的摩擦并不是形成摩擦水疱的机制。为此，防止摩擦水疱的形成一直是患者和治疗临床医生难以实现的目标。在本文中，我们旨在强调长期以来的水疱成因模式的局限性，并提供一个新的解释。
