I need help find a shoe that doesnt cause injury so I dont have to keep stopping. I did springer to fontana in a pair of low top merrell moab ventilators with no goretex. These worked great for about 100 miles and then I could literally feel my arches drop with each step. Shortly after came knee pain. Then for the last 20 miles I had terrible shin splints and had to stop at Fontana. So it took me about a month to recover and this time I went with Brooks Cascadia 3. Did multiple 6 mile runs with them with issues or pain. I also liked the quick drying as I sweat waaaay more than any normal human. So I picked up at Fontana and went a little heavier at 40 lbs to make it all the way thru the smokies. The 1st 20 miles I was flying up and down the hills. Then the bursitis began. Within 5 miles it felt as if someone had hit me in both heels with a hammer , but it only hurt if Im going uphill. Then on the downhill my knees would hurt. It was so bad I had to pull out at Clungmans dome. Can anyone Please recommend something to help me out. It took me a full month of wearing sandals to recover from the bursitis. I just want to get back out there. Additional info. I am a neutral pronator.
