So for many months, maybe a year, I've been letting my right ankle settle down. I've not worn hiking boots, avoided shoes with work heels, done limited strengthening exercises and gradually become accustomed to zero-drop shoes. The pain around the lateral malleolus seemed to have disappeared.
Earlier I went for a walk in the woods and wore new Vivobarefoot hiking boots. Within an hour my ankle was sore and by the time I was home at two hours I was contemplating walking in really barefeet. This is disappointing and concerning. Disappointing as I'd hoped the problem had resolved and concerning as I've entered a long distance walk in a few months time and I don't want to be recovering from injuries.
