Did not read through all 75 pages of this thread, but read the first 10 or so to find the difference between the Euro Gortex version and the US version. I picked up a pair of the non gortex US version of the Sidi Adventure boots, size 42, which fit my normally US 8.5-9 feet (I am more normally 9.0 US in boots, so I agree these tend to run the slightest large, and I tried on the next size up, these fit the best), at the Long Beach Moto Show in December, 2010. I believe I paid either $300 or $325. There was a Sidi rep there, and he was very helpful. He was a surprised I claimed I would wear these boots daily, his idea of commuter boots was much less protective. I commute very close to 5 days a week 52 weeks a year on either my GSA or Hypermotard. I wear out a pair of boots in about a year. I buy a lot of my moto gear at the Dainese corporate store in Newport Beach (worth a trip if you are nearby), but they have not had my size in deep discount boots lately, and my commuter boots were very worn. So at the show, I was looking for some good value, well made boots which would offer max protection, yet be comfortable enough to walk around my office all day and/or perform the odd day of field survey work. At the show, my size had somewhat limited choices in what I was looking for, and I decided a pair of the Sidi Adventure boots would replace my old MX boots for my mild dirt riding, while I continue the search for commuter boots. I now have about 2-1/2 months on the Sidi's. Good stuff: Very well made. Maximum protection in a very walkable boot which is easy on and off. I'm 53, and inflexible enough that I don't want too many buckles. The 2 buckles per boot seems good. Buckles well made and still work great. Reasonable comfort. I am a bit concerned that the boots offer so much support with the ankle hing, that my daily use may cause weakness in my ankles. Maybe not an issue. I do know that I would be confident in these boots offering great protection in a crash. They actually work pretty good for some hiking / topo mapping of some steep slopes I have been on. The lug soles offer good traction, and the boots give good support when I am lugging equipment. The boots themselves are not too heavy to be obnoxious. I have commuted a total of 2 times in heavy rain. Both times feet stayed bone dry, even though pants (draggin jeans) were soaked. Bad Stuff: These boots are so noisy squeaking down the office halls that my employees know when I walk up behind them, and I sometimes just stand in place and squeak them for fun. All in all, for $300 boots, seem like a great deal. For SoCal riders, I suspect they are water proof enough. I still am looking for some more comfort oriented commuter boots though.
