That is pretty difficult to answer directly without knowing why he is tripping, does he have something systemic going on or is it just because he is pigeon toed?
If the issue is pigeon toe (he walks with the toes pointing toward the mid-line of the body or his feet are turned in) then we can help by adding a wedge on the front outside corner of his shoes. We used to do this a lot back the 80's but I haven't seen any clients with this issue for a long time, it was very effective in gently pulling the feet into a more natural position, no more tripping!
