Protalus M-100 Elite | Patented Stress Relief Insoles for Boots | Big Heel Cup 

• BETTER IN EVERY WAY – The M100 Elite does not require a break in period. The new materials and design of the M100 Elite allow you to slide these into your boots and go
• PROVEN BETTER ALIGNMENT – Scientifically speaking, it is the alignment of the subtalar joint that prevents overpronation or oversupination. Through aligning your ankle, you place the heavy lifting back on your bones, thus reducing stress on your ankles, knees, and hips
• IDEAL FOR LARGER / WIDER SHOES: The M100 Elite boot insole is designed for boots, basketball shoes, hiking shoes, high tops, and other larger, wider shoes. For regular shoes, buy our T100 Elite shoe insoles
• LESS PRESSURE MORE COMFORT - Our innovative combination of heel cup technology and high-quality materials provide excellent impact reduction and moisture-wicking capabilities for unmatched comfort. Protalus insoles improve alignment of the ankle by 31% when compared to generic stock shoe inserts
