I've started doing a lot of walking recently, and I enjoy it, but my feet eventually start hurting and I can't keep going. Not in a way that suggests an injury, just getting really sore and swollen. The shoes I wear for walking are the most supportive ones I own, and some of the most supportive ones I've ever found.
I've tried googling a little bit, but all I've found is suggestions to not be overweight, because that makes your feet hurt. Which is not particularly useful.
Does anyone know anything that can help extend the time it takes for your feet to start hurting?
