Awesome Trail Shoe

I've put it through the wringer
True to size
Size Bought

I've been using an old SIDI cross country shoe with a super stiff sole for many years before finally wearing them out and switching to this. It's definitely a more trail oriented shoe and its super nice that's its actually wearable off the bike. At first I was worried the fastlace would get in the way but its actually designed to tuck away into the forefoot laces and then under the strap for a clean look and no chance of getting caught up anywhere on the bike. I have the BOA laces on a road pair of Giro's and don't think its worth the extra $50 on this shoe unless that's the only size option available, then I wouldn't hesitate to pick it up instead of the fastlace. And sizing is spot on, true for me with no hot spots yet.


I have Scott, Specialized, Shimano in 44 I am assuming a 44 in Giro would fit the same?

I wear a size 11-US which is a 46-EU in Shimano/Specialized/Scott/etc. Giro says that a size 46 is equivalent to a 12-US and, indeed, the size-46 Giro shoes I tried are too big for me. The sizing chart recommended a 45-EU and that's what I should have ordered.

Pretty good but not the best Giro shoe

I've used it once or twice and have initial impressions

I’ve had Giro Gauges for years and I’ve tried a few other models from them as well. These are definitely a comfortable and a quality shoe. The soles are somewhat stiff but not as stout as the carbon soled models. I would say these are geared more for a casual trail and cross country mtb shoe. For competitive cyclocross and race ready mtb riding I would want something a bit stiffer. However these are perfect for those weekend trail days where you may get off the bike and walk back up the jump line or have a few hike-a-bike moments. These are also good off the bike to walk up and order coffee or grab a long lunch and beer after the ride. The quicklace feature is nice as well. Seems like a good alternative to the BOA system with much less opportunity for trail failure or maintenance. The lace up is snug and quick to engage. I do feel like the long lace is a bit awkward to tuck away afterwords and the Velcro strap over the top may be unneeded as the tension at the top of the lace is already very tight. I think maybe the Velcro could have been a more clever storage pocket for the extra lace material instead. They run pretty true to size and the materials are high quality and a nice lightweight and breathable construction. The soles are for sure more grippy than my gauges were. Stoked to put more miles on these.

Great shoes

I ordered these and the Giro Gauges (both 45). The Gauges were way too low volume and uncomfortable on my toes. A gearhead let me know that the Ventana uses a different Giro shoe last more like their flat shoes and it was way more comfortable. The bungee stays put in the little hook and the velcro is exactly what you need to make sure your heel doesn't slip. I've worn these on 4 rides so far and they are holding up great - comfortable to ride in, stiff to climb in, and make me feel more confident on the trails.
