Jump99 Ultra Strength Plyometric Training Shoes - Boost Vertical Leap

In this review of the Jump99 Ultra Strength Plyometric Training Shoes the bottom line is straightforward: these shoes are for athletes who want measurable gains in vertical jump and sprint power with minimal fuss. Built around a plyometric training concept and paired with a mobile app for guided workouts, the shoes promise a 5-10 in increase in vertical jump when used consistently. The reviewer found them most valuable for explosive sports training, delivering real improvements in calf definition and reactive strength while remaining comfortable for repeated sessions.

Key Features

• Increase Vertical Jump: Designed to add an estimated 5-10 in to vertical leap when combined with the prescribed plyometric program, helping athletes reach higher on the court or field.
• Fast Twitch Focus: Targets fast twitch muscle development so explosive movements like jumps and sprint starts become more powerful and responsive.
• Improved Speed: Training with the shoes can lower short sprint times by strengthening the specific muscles used in quick dashes and bursts.
• Calf Definition: Regular use promotes increased calf mass and muscle definition, contributing to better stability and reactive strength.
• Size Range: Available in sizes from 5 to 13 for both kids and adults, offering a broad fit range for team and youth athletes.
• Mobile App Guidance: Works with a free mobile app on the App Store and Google Play to select workouts and follow specific training programs.

Who It's For

These shoes are best for basketball, volleyball, sprint and track athletes who want a focused way to increase jump height and short-distance speed. Coaches and serious weekend competitors who follow structured plyometric programs will appreciate the targeted fast twitch development and the guided sessions in the mobile app.

They are less appropriate for casual walkers or runners seeking cushioned long-distance footwear, and anyone expecting an instant transformation without consistent training should look elsewhere. Also note the product ships without a printed manual, so users should rely on the app for instruction.
