Don't hesitate to buy these guys. First try and they fit like butter. I've used pumas, vortices, and supertech r's and the ST's are much more comfortable than any of those.
TJ is currently out of the office. You can touch base with Michael @ RidersDiscount.com and he will get you the info.
Our original post on the Sidi ST boots featured photos of the perforated Air version, but we do have the standard boots in stock and ready to ship if you don't quite need that much air-flow. Just remember that these are not listed on the Riders Discount website yet, so you'll have to get in touch with TJ to order yours. Feel free to give him a call at 866.931.6644 ext. 817, or send him a PM through this forum. You can also send an email to FORUM at RIDERSDISCOUNT dot COM and we'll get back to you right away! The Sidi ST boots are shown here in black. We also have them available in white. Here's a comparison between the standard Sidi ST and the ST Air. The standard may not have the heavy perforations, but it does still feature the adjustable side vents.
