excellent advice indeed. i have both clifton and park avenue. IMHO, the fits are fairly similar. my current size works fine but i wish i had gone half-size up when i purchased them. not only you should try to get a proper sizing by a sales associate, you would want to wear them and walk as much as possible in the store. if you purchase shoes from an outlet, you can still return them as long as there is no visible wear on the soles - try them on in your apartment on a mat. you can always return them, even with the closeouts.
