Have you seen the EquiFit D-Teq Boots? The ImpacTeq Liners which are made with air mesh and foam reduces the shock and keeps the legs cool! The outer shell is very durable and protective!
I find equifit wraps to be the best in terms of polos because one side is non slip memory foam and the wraps themselves are much longer than regular ones. In terms of splint boots I don't find much of a difference in terms of support once you pass the 75$ mark
