I'm not sure why these are cheaper than the Hydro... My guess is they use an in-house waterproof membrane, and the Hydro uses a GoreTex membrane, which means forking over lots of $$ to Gore (?). I have ridden them plenty in the last month since I got them. Mostly in rainy conditions, with temps between 35-50 F. They get a little toasty on road rides around 50F, so if you plan to use them in warmer conditions in the rain, be warned.
The waterproofness has been just great, with the usual problem if you are spending this money on Sidis, you no doubt have spent money on proper road tightsleg warmers, therefore you don't have any water protection at the cuffs. So either you need to wear baggy pants that go over the cuff to prevent water getting in (in which case you'd just wear regular shoes), or water will drip down your leg into cuffs. Now this is only a problem during heavy rain, and it is a problem with all shoes, but it's there. (I consider this 5 stars because all shoes have this issue - it's the nature of Lycra clothing.)
Highly recommended, especially if you can get it on WBW mega deal!
PS I have wider feet, and these fit fine. Normal Sidi sizing otherwise.
Quite simply this Sidi shoe is the most comfortable shoe I own and it's a mountain bike shoe. Every other shoe I've worn in the same price range is complete trash in comparison. I will never own another mountain bike shoe and I'll be switching to their road shoes next. Thanks Sidi for actually knowing how to make shoes.
I purchased these thinking that I'd only use them while riding. It turns out that I'm wearing them more than I thought I would and not just for riding. They are a good entry level shoe, light weight and very well made. No issues or concerns with these shoes. Size does run true. I wear normally a size 11 and bought the Euro size 45.
These shoes replaced a pair of entry level Sidi MTBs that I had been commuting year round on for several years. I wish I would have switched a long time ago. I was shocked at how comfortable these shoes are both on and off the bike. They may be some of the most comfortable casual walking shoes I own. I often leave them on at work.
I use these with Crankbrothers cleats and I've had no interference issues. The cleat shims are definately needed and make sure to use the short cleat screws that come with the shoes. The typical cleat screws are way too long and will poke the bottom of your feet.
I've also taken these on longer rides and had no trouble with hot spots or numbness. Not as rigid as the Sidis but much more comfortable to walk in. These shoes have mesh uppers so your feet are going to get wet during the rainy season.
