Running shoe wear patterns – What is causing Grant’s shin splints?

Today on the Ask Coach Parry Podcast we chat about running shoe wear patterns and what could be causing irregular running shoe wear patterns in this case. Grant submitted his question and this is what he wanted to know:

I don't know if this is something you'd be able to answer, but if so, your guidance would really be appreciated. I have been running now for 2 years and am planning on doing my first Comrades Marathon next year. I just have one concern though that I'd like to have resolved before entering the Comrades Marathon on 1 September.

The shoe wear on my right shoe is much worse than the left shoe (the left shows no wear while the right shows major wear that appears to be from heel striking) and when I start ramping up the mileage to 50-60km + per week, I get the onset of shin splints only on the right side.

I don't know if it’s to do with one leg being longer/shorter than the other etc. Who can I consult about something like this, ie a biokineticist or a physiotherapist and what kind of shoe would suit me best as on the right side I'm guessing I would need stability while the left is almost perfectly neutral. Thanks in advance. Grant
