Hi L.,
Our daughter wears a full length AFO on her left foot (just below knee) and a short DAFO (ankle) on her right foot. If your son is new to wearing these AFO's, you should check for any redness or irritation after wearing them for a short time. They may need to be adjusted, which isn't unusual. A couple of suggestions for socks/shoes, which may help with the heat problem - we buy special AFO socks/shoes from the attached link. www.keepingpace.com The socks are great as they wick moisture away and the shoes (boy and girl styles) have some venting/netting on them for breathability. They are designed for AFO's (not bad looking either) as they are made deeper to accomodate the AFO/DAFO's. You can also remove some of the inner soles to aid in comfort. Hope this helps.
