I wore Brooks Ghost on my camino last year. I loved them but they're worn out now so I bought a new pair. They're Ghost 16. I don't know what my old pair were but I bought them in 2023 so I guess they were 15s? These feel the same but my hips hurt after a long walk and they don't seem to breathe as well. It's not that my feet sweat but I want to take them off ASAP after a walk on a warmish day. Has anybody else found a difference?
