Iron Heart 21oz Denim Sneakers

As one of the most serious vintage sneaker heads, Haraki San has created his ideal sneakers!

Featuring a specially developed, 21oz denim fabric for the upper, the sneakers feel breathable and have serious durability! Using a unique vulcanised construction process passed down from previous generations, these sneakers are extremely flexible and strong.

With a next level, bootlegged version of the converse outsole we all know, It feels familiar but so much better!

With time the denim will age to a lighter, high contrast shade. The white rubber toe and sides will age to a soulful, dirty look with time!

These are some of the best made in Japan sneakers we’ve seen so far!
