Sidi ST Air Boots

These boots have the same basic overall fit as the Sidi Vertebra/Strada products, so if you’ve had fit experience with those, you’ll be fine with the ST boots of the same size. The calf adjustment capability on these boots is very effective and has a WIDE adjustment range, so if you have big calves, this is your boot! Sidi says they can accommodate up to a 15 inch calf.

Otherwise this model runs true to Sidi’s size conversion chart and fits about like any other Sidi street boot style. Visit our Sidi Sizing Information page for complete size conversion info (ladies can use the chart at the bottom of the page).
Sizes range from 39 Euro to 50 Euro which covers both men’s and women’s US size ranges.

The Sidi ST Air motorcycle boots are an all new upper level sport boot, and I have to say I am REALLY impressed. The only difference between these and the regular Sidi ST boots is the Air version is fully perforated for hot weather riding. These boots seem to have the perfect blend of protection, comfort, and convenience. The problem I find with some top level race boots is they really aren’t very practical for street riders (unless all you are doing is aggressive canyon carving, etc). Race boots tend to be very stiff, and have a lot of adjustments and closures that make them cumbersome to get on and off. The ST Air boots, in contrast, have very easy entry, yet they are held securely on your feet at the same time. This is thanks to Sidi’s exclusive cam-lock buckles, which they brought over from their very successful dirt line. These buckles are the best in the industry. They are easy to operate, stay put when closed, and are very sturdy as well. There are two buckles on these boots, one on each side of the upper, with a very large adjustment range for different sized legs. Sidi claims that the ST Air boots can accommodate up to a 15 inch calf (12.5 inches above the floor). So for those of you with large calves, these are the boots for you! The ST Air boots feature more than just fancy new buckles though. The upper portion of the boot that folds down functions as a very sturdy ankle brace (take a look at the pictures we took, you’ll see what I’m talking about). After trying these on, I was very impressed with the amount of support that they provided. A replaceable shock absorbing heel cup and toe slider are nice features for those who like to push it, and a closeable vent on the side of the boot is a nice touch, although it is kind of silly on a fully perforated boot.
