The Cluffy Wedge is an orthotic modification
The foot is a complex area of the body because there are a lot of small bones which are joined collectively by a lot of ligaments and controlled by so many muscles. On top of that we take the bodyweight on the feet and subject it to so many stresses and strains. To make it worse we put the foot inside the artificial environment of footwear. It is for this reason that the vocation of podiatric medicine exists as there is just so much that will go wrong with the feet and associated structures. Podiatric doctors utilize a wide range of different interventions to treat problems of the feet and lower limb.
Foot orthoses can be used to take care of the wide array of problems that might be wrong with the foot. The goal of foot supports are to improve the posture of the feet towards a more corrected normal position or to lessen the load in structures of the feet which are leading to problems so that they can improve. The foot orthoses achieve this via having different design attributes that are designed to match the foot. A customized foot orthoses will do that. However, non-prescription supports can do that, generally by chance. They may or might not match the foot of the person with them in contrast to a bespoke insert will. There are many different characteristics varied, like the elevation of the mid-foot ( arch ) and also the amount of shock absorption. There are even designs referred to as Kinetic wedge and Cluffy Wedge.
Occasionally the much less expensive over-the-counter type insoles are better and other times the customized ones are better. It will all rely on the nature of the condition, the foot type and shape as well as the guidance of a good podiatrist as to what is the better choice. For those who have a problem with the feet and think you need some foot supports, then see a good physician.
