Superb Gravel Shoe

Have owned these for a year now and purchasing a second pair. These shoes are phenomenal and have been used for 7-9 hr gravel rides and long distance road riding. Lightweight, durable, and great adjustability with the BOA dials. Only downside is that they will not keep your feet warm in colder weather (less than 45F). So if you ride these in cold climates make sure you test fit with thicker socks.

FINALLY A supremely comfortable MTB shoe

It took a while and many returns later, I have at long last found a very comfortable and well made MTB shoe! First off, there are no pressure points on my foot with this shoe. This, in and of itself, is minor miracle for me. Just comfort all the way around. It has a snug fit yet also has some give in the material, making it kind of move with your foot. The BOA system works well and is quick and convenient. The sole is stiff. And my heel stays put. MTB shoes are very individual. Many seem really not made well, and most have been uncomfortable. I tried Giro out of desperation, and now I almost want to buy a backup pair. Comfort and fit is priceless. Typically I'm a size 11 shoe. I went with 44.5 here. I suspect 45 would fit as well. The 44.5 toe box has juuuust enough room but I like the snug yet comfortable feel so will stick with 44.5.

Nice shoes

Bought these for gravel riding. Now that I’ve ridden them a number of times, I’m going to replace my road pedals with SPDs so I can use them for road too. First, the BOAs. Superb. easy on, easy adjusting, easy off. Careful, its easy to overtighten, but a snap to fix on the fly. Second, fit. My old Giros were 44s, so I ordered 44s. These shoes have a very roomy toe box, they kinda seemed too big at first but they weren’t. Even with my duck shaped feet my toes have some wiggle room, but the shoes still feel snug enough so they don’t slip. I will use these for the winter and maybe try some 43.5s for thin sock weather. That roomy toe box keep feet warm when its cold, too tight means cold feet. Third, the materials. Though the uppers seem thin, my feet have been as warm as any shoe I have ridden. lastly, the look. These are some beautiful shoes, if shoes can be beautiful.

Question: Do you think this shoe would be suitable for someone needing a slightly wider shoe?

To Jm Ludvk, I'd say probably not a shoe for wider feet. Though you might try going up a half size.

I wear Giro road shoes, and I needed new XC MTB shoes. I was not sure about the fabric construction and some other reviews were very good for this newer shoe. I have to report, the fit is similar to the GIRO Empire road shoes, with just a little more room in the front. I wear a Giro 46, and in running shoes I wear an 11.5. This shoe is very comfortable out of the box, no joke. I am happy to have made this purchase, and thank you Giro. You can not go wrong, basic shoe with two BOAs.

Just perfect for me. Had some lace up Giros that I beat to high hell and got these as a replacement. Same size as the last ones and they fit perfectly. Dual boa is nice, i like to leave my toe box looser and can seperately dial in fit around the ankles. Super breathable which is great for the hot weather we get down here.
