So disappointed!

  • Familiarity: I returned this product before using it

These were sent right back. I'm a Sidi diehard, but I couldn't bear to wear these. They are incredibly stiff and uncomfortable...felt cheap. Surprising coming from Sidi!

Great for the Cold

  • Familiarity: I've put it through the wringer
  • Fit: True to size

We've had a long, cold, wet winter in Utah this year. I'd like to say I got out on the bike a ton, but i didn't. These shoes though? they made the rides I did get to do much more comfortable. GTX keeps the water out. High ankles keep the cold out. And SPD compatible keeps me from sliding around when I have to unclip. I originally bought the road version, but decided to swap to the Diablos for double duty on the road and mountain bike. Very pleased.

Great shoe at sale prices

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 12.5 USA 48 Euro

I bought this shoe for the much reduced price and am very happy with them. Not as warm as Lakes but waterproof is most important to me - I don't ride much under mid 30s F.

I also like the straps versus BOA as the BOA on the lakes broke my second week of use. I love BOA on my snowboard boots but trail abuse isn't great for a boa button that sticks out.

Sidi construction is top notch, very nicely made, they are stiff but then I haven't really broken them in at all and some will like the stiffness anyway. Very comfortable and decently warm.

I purchased 48s which leaves a lot of room for socks, I wear 12.5 US.

Diabolos are Decent

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I've had the Diablos for a few years now. I went with the Diablo over the Hydro for the flexibility and to use on my mtb/cross bike- I just put SPDs on the road bike in the winter time. I sized up to make room for big thick wool socks when fatbiking or when it's really cold. These do a decent job of keeping my feet warm. When it's below 32 I am putting booties on top. They do a decent job of staying dry and warm- but I'm going to try the Lake MXZ 303's next and feel that they would do a much better job at keeping my feet toasty.

I wore the Lake's all last winter in temps near 10 degrees in Chicago. You can go all day with these shoes and one pair of Assos wool socks. The BOA is acting up on both shoes though. May need to get them fixed already.

Hi Mark,

Thanks for the feedback on the Lakes! As for the BOAS, you can go to BOAs website and have them send free replacements.

How do these compare to the GHIBLI?

Good Dry. Not Good in Wet/Slushy Weather

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 43

I've used these many times this year in dry cold weather into the mid 30's and they work great for that. In dry/cold, I'd give these 5 stars.

Did a slushy/snowy ride yesterday and the shoes filled with water 15 miles into a 40 mile ride. There was about 1/4" of water stuck in the shoe, which must have come in from the top instep to toe area.

When I got home, the water would not drain out of the bottom of the shoe, so I'm confident it came in from the top. The ankle strap was sufficiently tight.

Alan, here is what works: VeloToze. Cut the toze off (pun) at the toe to make them like gators. Seals the top and let's them breath according to GTX technology. They are cheap and absolutely nails this problem common to all WXB shoes.

great inclement weather boots!

    I love these! I bought them because of a discount I was getting when I bought a new bike but am glad I did and would probably have paid retail for them if I knew how warm and dry they keep my feet during Winter rides. I don't think they have a carbon sole but they definitely transfer power to the crank better than my Dominators do. I also installed the spikes that come with the shoes and they really come in handy if I ever have to carry my bike up slippery climbs...

    Unanswered Question

    I wear a size 44 in Sidi Dragon 3 shoes....

    I wear a size 44 in Sidi Dragon 3 shoes. I understand the Diablo fits a little roomier to accommodate thicker socks, should I still choose the 44 in the Diablo?

    Very stiff

    • Familiarity: I've used it several times

    I bought these shoes with intentions of using them for cyclocross in the cold, rainy Pacific Northwest but despite being warm and dry, they were not conducive to dismounts and running; very stiff and uncomfortable like a road shoe. And being a high-top, I thought would give me some added ankle support but really kept my feet from planting firmly on off-cambered terrain. They were also very heavy compared to the Sidi Spiders I ended up using and after a few laps, they felt like lead weights on the barrier sections. I'm sure these shoes would be awesome for just straight cold, wet trail riding but I definitely don't recommend them for cross or any sort of riding where you'll be hoping on and off the bike.

    great shoes

    • Familiarity: I've used it several times

    I love the design of the shoe. My feet are doing good in temperatures down to 32F. The closures give a good feel and provide great power transfer to the pedals. Don't leave home without them!

    Very Happy!

      Have worn mine two winters with merino wool socks. No problems in the 30's.

      Toes begin to get cold after an hour in the mid to high 20's. Below that I add Gore boot covers with no problems into the teens.

      So Far, So Warm and Dry

        I got these mainly as a "rain" shoe for commuting, and less so for "cold" or wintery (snow) weather. That being said, my prior experience with Gore-Tex lined shoes is that they are far too "warm" for my taste - the bladder holds in the moisture too much - especially in a running shoe.
        Ive used these shoes on several down pour commutes and on a few days with temps in the teens and so for I have had warm and dry feet.
        I wear a 42.5 road shoe and got these in a 42. I had tried the 43 on but they had way too much heel lift. I use them with a standard / thin sock and find that they are fine for my needs.
        The upper cuff / neoprene band can "pop" the velcro if you try to cinch it super tight, but that's easily enough remedied. Dont expect the cuff to keep water out of the shoe if you wear em with shorts in the rain in the summer however.

        Frozen toes

          A very poor winter shoe for the price. I bought them a half size large to accommodate thick socks. In spite of this my feet froze even in mild 35'F weather. I replaced them with the Northwave Celcius Artic GTX which is far superior at 40% less $

          I'm very surprised with this review comment. I wore these all last winter. I was riding, on average, in 15o weather. However, it was only about 30 miles a day (every day of the week). How many miles did you do in them? Im curious because I love them so, but I've only used them in the worst of Utah weathers, for short miles.

          I currently use the Sidi Dominator 5 size...

          I currently use the Sidi Dominator 5 size 45 mega. The extra width is great for relieving hot spots and using a BG footbed & vargus shim. I still have a little room and could fit a thicker sock if needed. A standard width is too narrow and a 46 is too long.

          So the Diablo only comes in 45 or 46 & standard size with some extra room for a thicker sock. Would that equate to a Mega width or smaller? Since I would be using thicker socks & liner socks in cold weather I need extra width & length to accommodate that. I don't want to use booties over my current shoes and rather be able to use the Diablos for cold weather.

          So I am trying to decide weather a 45 would be wide enough or whether I should use a 46 and hope the length is not an issue with thick socks. Too bad they don't offer half sizes or mega width, which would be a better fit.

          Regards Steve

          Answer to my own question. I tried both the 45 & 46 and both are too narrow in the toe box with thick socks or a liner sock & standard sock. With standard socks they are ok, but then there is no air space to help keep warm. Too bad they don't make these in a mega size. I am returning both and will try the Shimano MW80, which is very similar but has a standard wide toe box as in most Shimano shoes.

          warm, dry feet

            got tired of my neoprene booties popping up and my toes freezing, so i got these. toasty warm and keep my feet dry in the snow. well worth the $ if you do alot of winter riding.
