Built for athletes chasing more pop
More lift. More burst. More confidence in your movement.
Athletes want to feel more spring in the legs, more power off the floor, and more burst in the first few steps.
They want training that feels connected to real athletic movement. Jump 99 Shoes are built around that pursuit.
Train for more pop
Work toward stronger takeoffs, more reactive movement, and the kind of explosiveness that shows up when you jump, cut, and accelerate.
Train with purpose
Every session should move you toward better athletic performance. These shoes give your explosive training a clear focus.
Why this kind of training matters
Explosive athletes train differently.
If you want to move faster, jump higher, and become more explosive, you have to train the right way.
Fast twitch muscle fibers are the muscles most associated with speed, power, and forceful athletic movement.
They are different from slow twitch muscle fibers, which are used more for endurance and longer-duration activity.
That is why explosive training feels harder and usually requires more recovery. But it is also why athletes use it
to build the kind of burst, lift, and strength that shows up when it matters most.
01
Speed
Train for sharper acceleration, quicker first steps, and more powerful movement.
02
Explosiveness
Build the kind of lower-body burst athletes rely on for jumping, reacting, and attacking.
03
Strength
Connect explosive training to stronger athletic action and more force in movement.
What comes with your order
More than shoes. A better start to your training.
When you order Jump 99 Shoes from HoopsKing, you also get the support materials that help you use them the right way.

Questions before you order
Helpful details
How do I access the training materials?
Your online video and training manual are emailed right after purchase. Keep that email so you can access the files again later.
What if I have never done this kind of training before?
There are three workout levels—Beginner, Intermediate, and Advanced—so you can start at the level that matches where you are now.
Can I do other training while using Jump 99 Shoes?
Yes. You can still lift weights on off days, do conditioning, and continue other training around the Jump 99 workouts.
Can I wear these in games?
No. These are for the workout plan. Do not use them in games. If you walk around in them, stay on a flat surface like you would train on.
How old should an athlete be to use them?
HoopsKing recommends athletes be at least 13 years old so their body has developed enough for plyometric-style training.
What size should I order?
Order the same size you normally wear in a Nike basketball shoe.
Ready to train
Start working toward more explosiveness.
If your goal is to jump higher, move faster, and train with more purpose, Jump 99 Shoes give you a focused way to work on it.

J99 Flex Ultra Strength Plyometric Training Shoes, Gray/Black
$179.99
HoopsKing TrainingTrain Explosive — The Plyometric Shoe Built for Liftoff
J99 Flex Ultra Strength plyometric shoes keep you on the balls of your feet and load the calves, building explosive jumping and sprinting power — with a high-traction outsole and shock-absorbing midsole so you can train hard, longer.

Why It MattersExplosiveness Comes From the Calves and Forefoot
Flat training shoes let your heels do the work — the opposite of what builds a fast first step and a higher jump.
J99 Flex shifts the load onto the balls of your feet, so every drill trains the calf and forefoot strength that powers explosive movement.
What It DoesBuilt to Make You Better
Forefoot platform loads the calves
Builds explosive jump & sprint power

The DifferenceAdd Resistance To Every Step.Not To Your Form.
Ankle weights and loose gear throw off your stride and stress your joints. SWAG shorts sew the weight flat and even into a compression short — so you build speed and power with mechanics intact.

30-day money-back guarantee (return shipping paid by customer).
Locked-In FitSecond-Skin Compression
A snug Lycra/neoprene compression short holds the weight flat against your legs — no shifting, no chafing, full range of motion through every stride and rep.
Even, low-profile weight distribution
Stays locked through sprints & jumps
Breathable, chafe-free compression
Built To PerformPower From The Ground Up
Loading the hips, glutes and quads — where your speed comes from — trains real explosiveness off the line, without ever changing how you move.
Adjustable LoadDial It In: 10 to 15 lbs
Evenly distributed weight pockets adjust in ½-lb steps from a 10 lb base up to the 15 lb max — add resistance as you get stronger.
FrontBackSide
How It WorksSmart Overload, Easy On Joints
Removable weights drop into pockets along the sides of the shorts — sitting evenly over the muscles that produce speed and power. Your body adapts to the added load while it stays low-profile and close to your center of mass.
Targeted overload. Weight sits over the glutes, hips and quads that drive sprinting and jumping — so those muscles get stronger and more explosive.
Easy on the joints. The load is even and held tight to the body — none of the swinging, shearing stress ankle weights put on knees and ankles.
Every age, scalable. Adjust in ½-lb steps from 10–15 lbs, so youth through pro can train safely and progress over time.
Every SportWhat It Does For Your Game
Lower-body resistance pays off everywhere explosiveness matters.
