It may be a topic that has been done to death, but anyway..
I have been umming and ahhing over whether to try hiking shoes instead of boots, as something of an experiment.
I have kneecap pain that predictably flares up going downhill, and pronation issues to go with it. I've tried six or seven different boots ranging from the lightest to mountaineering level and still experience the same problems. It may be a lack of fitness but being very tall and lean (to put it mildly) at 57kg, I have gotten to thinking that every extra gram of weight on my feet is contributing to the pressure on the knee area. And as far as "ankle support" goes it seems to be something of a sales pitch more than an actual feature of many boots.
Anyhow I would love some input from those who started with boots and transitioned to shoes, pros and cons, as well as anyone suffering from the same issues. And also if anyone wears a brace to combat this problem.
Cheers!
