The Radon Drystar is a high, solid touring boot. Quite slim and tight, ergonomic and quality in all areas. Literally and figuratively.
The outside is microfiber. Plastic, but the smart kind, and with a focus on longevity and tear- and abrasion-resistance. The Radon Drystar is made to last. A sturdy shin plate (TPU) and a subtle toe slider (TPR) betray its sporty pedigree, while an integrated Drystar membrane - weapon of choice when it comes to waterproofing at Alpinestars - highlight its touring capabilities.
A waterproof boot, with a lot of protective material on board. Heel, toe, ankles, shin plate... it's all there, and yet it never feels uncomfortable. The padding and the technology used (light weight yet structural protection) go a long way towards making this possible. It has undeniable advantages, all that knowledge and expertise from MotoGP. It should come as no surprise that the Radon carries a CE certification (EN13634:2010).
A removable anatomical footbed provides support and comfort, but the same goes for the lining, the finish at the top and the very natural slope halfway the foot. The accordion parts at the front and back also contribute to the comfort.
You open and close the boot by means of velcro: two strips and a wide strip under the shin plate. This is a logical choice for a touring boot of this caliber and it makes putting on and taking off very easy.
