I am also a runner and it does come up often in running circles. When training it’s not uncommon to build up to several 15 and 20 mile runs gearing for one race. Some do more than one race a year so you can imagine injuries are common with that much repetitive behavior. Shoes, or boots in your case, seem to be key. Even new runners go to running shops for their shoes and select shoes, with help, ideal for their feet. I always select from the stability line. Once you have a brand and style you can spend 4.5 hours running in without injury, it’s important to replace them when the cushioning compresses enough to become ineffective. Runners end up spending about $130 every year or so on shoes.
I would take a break and let some of the inflammation subside if you are having pain. While resting, retire those army boots and find a quality pair of light, comfortable, hiking boots that provide stability, and the right amount of cushioning. Merrell’s are popular but don’t get anything too expensive because you may want to replace them sooner than later. The surfaces you hike on can also slow your recovery. Stay away from hard surfaces even when not hiking. Minimize your boldering, evening walks on cement sidewalks, window shopping at the indoor malls . Even standing on hard surfaces can cause inflammation. They make an ITB strap that can help with your recovery, and once you have little to no pain they say you should keep up with the stretching. Several runners I know also use a roller, which they say helps to keep ITB from returning.
