Changes

After 200 miles the sole of the Clifton 3 remains virtually unchanged. It's a little dirty and there are some tiny spots where the exposed midsole as worn, but it's all extremely minor. The upper remains comfortable and functional, with no signs of wear even though I've cut the toe box open. The main issue with the Clifton 3 longevity is in the midsole cushioning. Most of the shoe is okay, but the spot under the ball of the foot has undergone significant compression. This is worse than if the whole shoe had compressed as it means the ball of the foot is lower than the rest, twisting the foot. This seems to create some problems for me, and my left knee is reacting badly. For the first time I have taken repeated measurements of the cushioning under the ball of the foot to give a picture of how a shoe degrades with mileage. So far, the decline has been gradual over the 200 miles, and I've not reached the point of rapid decline that I expect as the shoe starts to fail. The compression under the ball is noticeable by touch, feeling like a divot in the midsole. The compression is about 3-4mm, but that's enough to concern me. My , though my [[MilestonePod]] hasn't detected any significant change in impact so far. Update: I'd like was able to try to run further continue until I reached 240 miles, as which point the compression in them, but I'll have to see if the midsole was tilting my foot too much for my knee will to tolerate the problemand I stopped running in them.
