What Makes a Strengthener Special?
The Strengthener is the core of our 3-Step System. It’s where transformation begins. Its rigid structure challenges and strengthens your feet gradually, while the strategic design helps alleviate conditions like plantar fasciitis, flat feet, and shin splints. Built for wear-in progress and long-term use, it's best used in deep, supportive shoes and becomes more comfortable as your foot strengthens. Remember: progress, not perfection — every 30-minute increment is a win.
Supercharge Your Comfort with Our Cushions
Pair your Strengtheners with our Super Athletic Cushions for an unbeatable combo. Use the Strengthener for structure and correction, while the Cushions add shock absorption and comfort.
