Hey,
my first post but I can share my experience. I do have pretty bad haglund heel on both sides and run about 120-180km/week.
I did have problems with a lot of trail shoes, especially when I do a lot of vertical.
For me there were some game changers:
– find GREAT socks. Sounds stupid but for me this was a huge game changer. I wear the satisfy merino tube socks all year round, they are pretty thick but do not get hot. Yes they are expensive but better than turning around half way up the mountain.
– best shoes I‘ve tried so far are the Nnormal shoes for my heel. I get blisters and pain on almost every other shoe. Salomon has some that work for me too. But there ARE shoes that work for me, so maybe ypu can experiment in a shop or so.
– I do use foot glide on my heel. Maybe that sounds stupid, but a little slipping in the heel area is preferred for me on long climbs instead of a tight locked feeling. I tighten my shoes down more on descents or rocky/technical terrain.
– last but not least: really work your calves/achilles/sole of foot/hamstrings. I do a lot of stretching/soft tissue work etc and that helps. The bump seems to get a bit smaller on my recovery weeks.
Maybe any of this helps!
Best
Flo
