The Cluffy Wedge is a trademarked device that is designed for footwear, in insoles and in foot orthotic solutions. It was developed by the Podiatrist Dr James Clough, DPM primarily as a method to treat functional hallux limitus. The Cluffy Wedge is placed under the big toe or hallux to hold it in a gently dorsiflexed angle. https://podifelt.com/cluffy-wedge-made-from-podiatry-felt/
