These boots are big and clunky, though you may like the style. You get these out of the box and you think they look huge. But they are relatively light for all that the provide. They are not waterproof, because they do have mesh ventilation (which works very well). I've been wearing them in 90 degree plus heat and they have stayed mighty comfortable.
Initial wear is rather stiff. Lets face it, they are pretty much a stiff boot design. But they get a little less stiff after a couple days and can be relatively comfortable to walk in for short distances. For motorcycle riders, the stiffness might make it difficult to feel the shifter, but for scooter riding it won't matter as you legs are staying put. They fit underneath jeans pretty well and make your feet feel very secure. Their rigidity is helpful on bigger bikes, they reinforce your ankle. You aren't holding the bike up with your foot, they make sure you are holding it up with your leg. You won't have to worry about inadverdantly rolling your ankle.
The buckles are aluminum and are easy to adjust. The best part is that the boot has a side zipper, so once you adjust the buckles and laces to your liking, you never have to do it again. After wearing two or three times, they get a lot easier to get in or out of. The rear heel is reinforced, which means that you can kick up your kickstand without dinging your ankle (noticed raised logo on rear). Toes and sides are reinforced as well. There is a mid ankle version of this boot called the Icon Field Armor Chukka, and might be more manageable for those who don't want a full boot. Overall, I think it is a nice, comfortable boot that I don't mind wearing (particularly on my Big Ruckus and at higher speeds). I will probably pick up some of the Chukkas for around town and LR riding.
