I’m so glad you answered this post.
Nate has size 15 and 16 feet also and whenever our insurance gives the ok to cast his foot and ankle, they will be making him an AFO with ankle hinge.
He has a really bad deformity that happened while he was paralyzed. It caused his foot to turn under, toe in and his toes dropped too. The brace will hopefully help him be able to stand and walk easier.
He has lots of shoes to pick from but if none work, I will need to know what store you got yours from.
I’ll be PM’ing or e-mailing you.
