Every situation is unique and so should your approach to height enhancement. That’s why we’ve created a custom system which allows you to adjust your desired height boost from 1” to 2.5”. Ramp up your height over time, or change your approach based on occasion or footwear.

Undercover Fox is designed for all-day use. Our lifts are supported by custom “air bubbles” which will deliver an extra spring to your step and not have you feel like your’e walking on bricks like some of our competitors.



We know that being “Undercover” is of critical importance. That’s why discretion is at the core of everything we do. Whether it’s our discreet packaging and billing name or subtle design built to blend into your existing footwear, you can be sure that you indeed remain an “Undercover Fox”

Only 14% of men in the US are 6 feet tall or over, which means 86% of US men don’t meet most women’s ideal.
