I’m sure you experience this at the department store. The salesperson goes “Does it fit? Those shoes look nice on you. Should I bring you a 7-1/2 size?” and after a few minutes in the back room, he comes back and says “Sorry, we only have size 8.” If you really want a pair of shoes that fits, you ought to stop by the Running Room. Bring your old running/walking shoes with you. By looking at the wearing pattern of your old shoes and getting your feet wet, they can find out what type of feet you have. Flat feet, high arched, pronation, supination, wide feet all require special attention. Leave your ID and they’ll let you run up and down Kapahulu Avenue to try out the shoes. Marathon is just around the corner. Make sure to buy your racing shoes and break them in before the race. Trainers are a little more supportive and have more cushioning material and thus tend to be heavier than racing shoes which tend to be lighter and more flexible. But you should wear them once a week to break them in months before the race. Happy shoe hunting.
