There are a stores that carry boots. US Patriot Supply, AAFES on military bases (use acceptance letter for base access), Army Surplus stores, Boot Barn (smaller selection but still have Belleville, Rocky, Danner, Bates, etc.) Last year I took my DS to all of these, but finally went to a base using his acceptance letter, and there was a US Patriot store in the Exchange and was able to try on many different pair, and found the ones (Garmont T8) that fit him best. Honestly, you are really just trying to get through Beast, once on Post, the C Store has several brands of boot so if they wear them out, they can get a new pair. Since we found one my DS likes, he just orders them on Amazon and they ship directly to him at school if he needs a new pair. If your Cadet Candidate tends to wear shoes out (like my DS) then West Point will accelerate the process of wearout is they will be constantly wet, and the terrain is quite rough.
