I have been breaking in a new pair of Asolo TPS 535 V boots. These are full leather hiking boots and are actually quite comfortable overall. I have around 30 miles on them so far and feel like they are pretty well broken in. But concurrent with breaking in the boots, I have started to notice some pretty significant soreness in my calves when I go running, and also my left foot feels kind of sore at times. I'm thinking that the fact that this surfaced while also breaking in the boots might indicate causation ... otherwise, I haven't changed anything in my workout routine. I typically have been running 30-40 miles per week and ran a marathon in late January, and I never get this type of calf soreness just from running. I've moved to running 3-4 times per week (15-20 miles) and doing elliptical on the other days to try to deal with this. It's kind of freaking me out since I start the PCT three weeks from today. I will be hiking in trail runners on the PCT until the Sierra where I currently plan to change to boots (however, if the snow conditions do not change, I may stick with trail runners throughout).
Has anyone else experienced sore calves when breaking in new hiking boots, or switching between over-the-ankle footwear and lighter trail runners?
