    Found sizing to be tru

    I've used it once or twice and have initial impressions
    True to size
    Size Bought

    I would echo all of the other reviews, except on the point of sizing. First time in a Giro shoe, so cant speak to sizing across the brand. I wear 10.5-11 in street shoes. I have been wearing a 10.5 in Freerider Pros and 44 in Specialized. Ordered the 43 based on reviews (Would have gone with a 43.5 if available, was skeptical ordering the 43) and it ultimately was too tight for me—both in overall length and the arch. Went with the 44s and perfect for me. Toe box is relatively wide for a cycling shoe—a plus. Great shoe.

    Unlike many cycling shoes, this one has a relatively wide toe-box. Very comfortable. I do NOT have wide feet; nevertheless many cycling shoes have narrow toe-boxes, pinch the toes. Pleasant point of difference. Runs slightly large.

    Giro Found The Sweet Spot

    I've used it several times
    Runs large
    Size Bought
    Size 41

    The Ventana is now my go-to shoe for the majority of my mountain bike rides. I sized down from my previous pair of Giros and the fit is dialed, definitely more comfortable than the other models I have tried. I wear a size 8.5/9 in a US Men's and my feet are a little wide. I previously rode with the Giro Chamber II which was great for hard core shuttle laps or bike park days, but was too hot and bulky for long days spent pedaling around in the mountains. The Ventana feels like the perfect cross between a XC race shoe and a beefy downhill shoe. The ventilation is great for long hot and sweaty rides while still being durable enough for riding and hiking through gnarly terrain. So far I've spent most of my riding in wet, sloppy late winter/early spring trail conditions and they're holding up great. They seem to be keeping my feet relatively dry even with all the added ventilation. Overall I think Giro has created one of the best shoes out there for those wanting to just get out and ride anything the mountains might throw at them. I'm stoked to keep riding these and I'm sure they'll last a while.

    Comfort and Performance!

    Wow, first slip on and they were amazing. I thought I might have found myself in the incorrect size, as the new fit was much roomier than my old Empire VR90's ... but I hear that was the point! With a fit more similar to their flat pedal shoe, you are left with a sleek, relatively lightweight, yet tough do-it-all shoe. Admittedly, my first ride included a bit of hike-a-bike through some tougher rock gardens, but I was surprised by the traction I had, even with a stiffer shoe. Like just about everyone else has mentioned, this shoe is unlike others on the Giro line, so if you have tried some before and felt they were a little narrow, well you're not alone! Give these a go, you'll be happy you did! Overall, I am really pleased with the feel and fit, I did try two sizes, and with my insoles I am between the 41 and 42... (42 : FiveTen Kestrel Pro - a touch short and 42.5 : Giro Empire VR90 - narrow). I will be going with the 41's, so consider sizing down!

    Great Design - Beware Sizing

    I've used it several times
    Runs large
    Size Bought

    I've only had the chance to try these out a couple times due to the snow but so far I like the design. I think they look good with less flashiness than XC shoes but sleeker than a skate shoe styled DH shoe. Materials used all seem solid like they'll stand up to some bushwacking but time will tell. The sole is plenty grippy and stiff enough, but not too stiff to spend all day in. I'm torn on BOA dials on mountain/gravel shoes as they lack bulletproof durability, but they are really nice for fine tuning fit. I do wish Giro had upped the price a bit and gone with the IP1 which ratchets both ways. Adding Giro's Supernatural insole system is another feature I'd pay extra for. Now fit - these fit way differently than previous Giro shoes, they've got much more volume. A size 43 Terraduro fits me perfectly so that's what I first tried in these - they were quite loose at toes, heel, and ball of my foot. So I went down to a 42 which work far better. However they don't have room for anything beyond a thin sock. At this price I would have hoped to perfect the fit with a half size. So if your feet were a bit too wide for Giro's previous shoes, try these. And if Giro's previous shoes fit you well, be wary.

    Upgrade your Terraduros!

    Really happy with these shoes right out of the box. Beautiful fit and finish, and top notch materials. They fit my foot much better than other Giro shoes I've owned in the past. As Josh mentioned below Giro is using a new last in these shoes, similar to their flat pedal shoes. Which is wider than what has traditionally used in their shoes. I wear a wide in most cycling shoes, and ski boot and these fit my foot perfectly. They also fit bigger than other shoes in Giro's line up. I wear a US 10 in street shoes, and a 44 in most cycling shoes. In the Ventana, to my surprise a 43 fits perfectly. I'd recommend sizing down a 1/2 to full size depending on how wide your foot is.

    Perfect trail shoe!

    I've used it several times
    Runs large

    I've ridden the new Ventana more than a handful of times now, and I am super impressed! Phenomenal fitting shoe; lightweight; stiff enough under pedaling pressure, but with enough flex in the toe and torsional flex at the heel to make it a great shoe off the bike too. The shoe fits a little wider than other Giro shoes I've had (Terraduro, Privateer, Empire VR90), and runs a little bigger. I had worn a 46 in the all the other shoes mentioned here, but wear a 45 in this shoe. Admittedly, I wore a 46 in those shoes to get some extra width -- 45.5's were the right length -- I would recommend sizing down a 1/2 to a full size. This is the perfect trail shoe!

    Thanks for the review. Eyeing these shoes. What size do you wear in US shoe size? I want to try to order these in the right size.
