“I've been using Sorbothane insoles for almost 40+ years in all my shoes I. e. dress, casual and athletic. That should speak for itself. I recommend these to insoles to everyone. However, I did not see a difference between the Ultra & Max Duty insoles”
Thank you again, Anthony! Yes, they're pretty similar. The Maximum Duty features 1.75mm more cushioning at the heel. We appreciate your feedback & your business!
