SUPRO® Comfort Technology is Deer Stags' proprietary cushioning system designed to deliver the comfort of a sneaker inside footwear that traditionally isn't known for being especially comfortable, such as dress shoes, loafers, boots, and slippers. The name stands for Super Radical Rebound Technology.

At its core, the system combines several elements:

• Shock absorption to reduce impact on your feet, ankles, and knees.
• Energy return that helps propel your stride and reduce fatigue.
• Arch support to provide greater stability and improve comfort during long periods of standing or walking.
• Lightweight construction that prevents the shoe from feeling bulky.
• The patented S.U.P.R.O.® Sock, an EVA-based orthotic footbed designed to cradle the foot with contoured cushioning.
