TECH:

I have borrowed from adidas' long list of very well developed technologies.
For the midsoles I have used the BOOST™ technology for ultimate energy return and maximum responsiveness.

To secure breathability, flexibility and an enhanced fit the JJ 1.0 & 2.0 has a Primeknit upper with leather details.

JJ 3.0 has a leather upper to secure stability with mesh details and mesh tounge to secure breathability.

JJ 1.0 & JJ 2.0 has elastic strap with velcro closure which wraps the entire foot and relieves pressure.
