Our Two Cents
The Black/White color in this style is being discontinued and we picked up the remaining inventory as a closeout. Enjoy the savings on these boots while the inventory remains. You can use the drop down menu above to see what sizes are still in stock. I added a link to the all-black color Astro below for your reference. :: Paul, 06-19-14
These new Astro boots by Sidi (formerly called the Nitro boots) are super sharp. The overall design is low profile and lightweight. They’d be ideal for sport and street riding. The sole composition is very firm and should wear well and is surprisingly stiff for the thickness and weight (which is good for bearing weight on pegs). The toe and heel areas are stiffened for some impact protection and there are internal protectors positioned over the ankle bones. The new feature I really like about this boot is the lacing system. The video from Motonation shows it off pretty well, but what I like is the fact that it is adjustable just like shoe laces (which hasn’t been obsoleted in hundreds of years), but is self contained with no pesky lace ends to cause havoc with machinery. The adjuster contains the ends of the laces internally, which is VERY neat and tidy. I found the device very quick and easy to use, and when tightened up, the boots felt very secure on my feet. The overall construction of these boots would lend themselves to spring/summer/fall use. There are several smaller panels in the boot that are perforated material that will allow a good bit of air flow. The upper material is a synthetic leather, Technomicro (functionally the same as Lorica used in other Sidi styles). I really like this design and if you are in the market for a minimalist riding shoe like this, then I think you will like them too. :: Paul, 12-22-12
