Onitsuka Tiger Mexico 66 are a running sneaker that was launched in the 1960's. With a sleek low-profile and flat sole, the insole is surprisingly spongy, providing you with good level of comfort.
Having worn them regularly, I find the materials and construction to be of great quality, and the sole turned out to be quite durable. They don't lose much height after months of wear, giving you around 1.5-1.6cm of height. Brand new, they seem to give around 1.6cm, or roughly 0.6 inches.
