A Cluffy Wedge is a trademarked device that is used in shoes, on insoles and for foot orthotics. It was developed by Podiatrist Dr James Clough, DPM especially as a way to treat hallux limitus. The Cluffy Wedge is positioned under the hallux or hallux to keep it in a mildly dorsiflexed position. https://podifelt.com/cluffy-wedge-made-from-podiatry-felt/
