After my 19 mile walk yesterday, I can now follow up on my original post on my new Sorbothane double strike replacement insoles. The terrain on the walk was varied – uneven footpaths, small rolling hills (for Northamptonshire they were hills!) and tarmac.
Once my body had adjusted to the amount of walking I have started doing since Christmas, I can just about walk 20 miles or so without feeling too much discomfort in my limbs, muscles etc. The same cannot be said about my feet however – after 10 miles or so the heels and ball areas of my feet start to become uncomfortable, and after 15 miles complete agony.
