Hello Grandmarm & IDK,
IDK, it depends on how soon your brother got his boots sometimes it may take a month or two to break them in. If it has been longer than that he should go through his chain of command to get replacements from the QMaster "Could be a difficult out here" If all else fails you can purchase him some Tan or Desert colored boots NO BLACK! make sure that they have good vibram soles and cordura side panels so his feet can breath; Check out "Ranger Joes" they provide a good variety. Keep in mind that foot gear manufactures sizes are not exactly the same and that it could possibly take a month or more for him to receive them after you mail them out. I hope that this helped and I hope that your brother gets a good pair of boots because I know how much misery can be caused by bad boots.

Thank you for your time and support it means alot to all of us out here to know that there is people back home that think about us and take the time to provide a few creature comforts and tibits of sanity.
