I got achilles tendonosis running in very well cushioned shoes. To cut a long story short, it is ok as long as I keep away from speed work and stick to easy jogging (and gradually built up). A physiotherapist told me to switch to forefoot running (in trainers) but I couldn't manage it. I asked him for advice on how to run forefront, he said "just do it - you're overthinking ... running is natural". Since then changed physiotherapist. More recently started running barefoot, initially as an experiment to strengthen the feet, now I'm hooked. Here's my question: if you approach barefoot running carefully and develop proper technique, is barefoot running better for your achilles than shod running, over the longer term?
