We are going to be looking very closely at posterior heel blisters today. Interestingly, this is where my special interest started with blisters. <\/p>\n\n\n\n
The common, and might I say incorrect, understanding of the cause of posterior heel blisters is that your heel rubs the shoe, or your shoe rubs your heel. Well, if we have a closer look at what’s going on at the posterior heel, we’ve got the posterior calcaneus, the skin surface, and the subcutaneous tissue layers. Obviously those soft tissue layers run parallel with the skin surface.<\/p>\n\n\n\n
If we add in the shoe and the sock, it quickly becomes apparent that it’s actually impossible for your shoe of your heel, or for your heel to rub your shoe – because the socks in the way. So what is rubbing what. And is rubbing even important to blister formation? Because we know that blisters are caused by repetitive shear deformation.<\/p>\n\n\n\n
