the grate gatsby
Oct. 8th, 2019 10:08 amPREVIOUSLY, ON ROADRUNNER TWICE: I got a foot grater, and I used it to grate my feet. Pretty gross.
Last Saturday we went on a bigass run in the woods, like eight miles on fairly dire terrain. (Ruth is doing the Elk Kings 25k next Saturday, so we were doing a recon run on the second half of it. We already know the first half is completely demented.) And normally, that's just over the line where I'd expect some minor blistering on the ball of my foot. But nothing!!!
V. possible I just got lucky, because that does happen. But it's pretty likely that the grating helped!
That book Melissa suggested to me was making this argument that blisters are all about the accumulation of shear forces — it's not directly about how much friction there is on the surface of the skin, it's about how much shear force gets transferred to the _inner_ layers. So if the outer skin can slide freely against the sock or whatever, that expends a bunch of the shear force on the outside before it can transfer to the depths. Anyway, I bet making the pads of my feet much smoother made me less likely to blister or chafe! Especially on that right foot, where part of the callus peeled off earlier in the summer and left a rough edge.
