It's pretty awesome for kettlebell lifting and strength training workouts also.
The Onitsuka Tai Chi is a martial arts shoe that offers exceptional movement.
The amount of movement that the Tai Chi makes available makes it awesome for kettlebell lifting, strength training, "barefoot" running, and any sport where balance and body awareness is an important.

And it comes in other colors besides yellow
This is of course the official swordfighting shoe of Beatrix "Black Mamba" Kiddo, aka "The Bride" in Kill Bill. So if you're a hot sword fighting assissin who's been double crossed by your supervillain lover, this shoe is a slam dunk for you.
More Information = Better Ninja
My clients wear shoes like this because they know that the more information their feet get from the ground, and the more movement their feet are allowed – then the better body control and body awareness they will have in their fat loss workouts.
= More Control and Body Awareness

Puma's are kind of oldschool-retro.
So if you're more the retro kung fu 70's supervillian mastermind with a truth serum shooting dart-gun in one hand and a hanzo samurai sword in the other – then I recommend the Puma Saloh.
The Vibram FiveFingers is the ultimate movement shoe.
If you've got the balls to wear the VFFs
you'll be shocked at how much stronger, more balanced,
more graceful, and more powerful you are after wearing them for a month.
It's a good choice if you're an ancient kung fu master with a long wispy beard and a maniacal laugh, then the Vibram Five Fingers might be just the shoe – especially if you want to bust a Five Point Palm Exploding Heart Technique with your feet.
The ultimate workout shoe is of course bare feet. But these three option often look cooler. And many gyms require you to wear shoes.
Even If You Aren't A Ninja…
So if you're a hardcore workout girl or guy who wants every edge to get leaner…
Or if you are a ninja with a samurai sword in a yellow jumpsuit…
Then it's time to upgrade your footware.
