I’ve starting training for my first iron man in September (not yet canceled fingers crossed). Training has started around 2 months ago and around a month ago as I started longer more intense run sessions my right foot arch started to get sore. Until training I only did running occasionally as I’m a road cyclist. Last year I had fitted out shoes and in the analysis it seems I slightly pronate and so bought a pair of Hoka Arahi 3. I don’t have a flat arch and it doesn’t seem too high. The Hokas’ certainly helped as pain from my tendons disappeared which I always faced when I ran in the past for more than 20 mins. I understand that as my running legs and feet are new to training so much I can face some pain initially but it’s almost 2 months now and the pain is not going. I have rigged an arch support that came with my Giro road bike shoes to try improve but not much difference. Also I do some exercises such as massage the arch with a golf ball, lift a cloth with the toe etc. I am thinking of ordering orthotic insoles and so any advice would be helpful. Also, I never used stability shoes in the past so wondering is that could that be the issue and so should I get a pair of neutral shoes to try out and compare
