Grade: 1
Running up rocky hills in o-shoes is awesome, but it does put a strain on the ligaments of the foot. Now the ligaments of the left sole are sore in the morning. They don't hurt when I run in regular running shoes, though. I don't want this to get worse, so I'm going to monitor it.
The foot recovered, probably because I wasn't doing too much hilly running in shoes with little cushioning and support.
