Yep. Stop watching all sorts of advice from your chair. I have been hiking for many years now at ca. 2000 km per year. The body simply optimizes itself in time for all but very few people. A little adjustment might be necessary for particular cases, but you will figure this out finally yourself.
But the highest priority by far remains doing the basic things. Regularly - in any weather in this case - without excuses. That is the core. All other issues are premature optimizations (or to be clear, no optimization at all)
