Purchased for spirited street rides and for some track days. Comfortable from the start but broke in and are now even more comfortable. Venting is perfect and they look great. Most protective boots I've ever ownerd.

Just did my first track day this weekend. From the first session they felt already broken in, I was very impressed.
Sizing: I wear a US 11-12 with a wider foot. I initially got Euro 46 (US 11.5) and they were pretty tight. I didn't want to potentially waste $450 to find out, so I got the Euro 47. There is some heel-lift as mentioned in the STG video, so if that bothers you maybe go smaller. But for riding in them you wouldn't know it.

All the reviews are true. This boot is top shelf all the way. Yesterday I took them on their maiden voyage, 88F 31c temps Very sunny, My feet were very happy the whole ride. You can change the way it cools buy changing your foot position. Super comfy in every respect. Watch the review video to make the correct sizing choice. Spot on.

First off, what a great company STG is...the selection and prices are awesome, they spend a ton of time with the product reviews which actually help, and they do not mess around with order processing times...mine was shipped within 24 hrs of the order and I had the boots a few days later.
The boots are really nice and have a very high end feel. They actually feel pretty broken in right out of the box, and although I just got them and haven't ridden with them yet, I know they're going to be perfect on the track.
A quick note about sizing, since I fall right in that 10.5-11 size range depending on manufacturer. As a point of reference, I wear an 11 in Underarmour, Nike, Vans, and Salomon shoes, and sometimes a 10.5 in certain work boots and my new ON running shoes. And you never know how it's going to shake out when you're dealing with Euro sizes with US "equivalents." Well, for these SMX Plus V2 vented boots, the Euro 44 fits like a glove... absolutely, 100% perfectly. But. The "US" size says 9.5 - which had me sort of concerned when I opened up the box, especially considering that my Alpinestars Rideknit shoes are a Euro 43.5 which is somehow a US 10.5. I don't know what they're up to over at Alpinestars, but follow the sizing advice from STG regarding the fit - it's right on! The AStars size figure-outer people need to ease off on the Peroni.
Last note about the fit - it's absolutely perfect and comfortable around the foot, but if you have big calves - which I do - the zipper can be tough to zip up, especially with leathers on. I'm hoping it'll get easier when they break in for real, but it's a bit of a struggle right now... although part of the deal is just trying to hike up the lower leg portion of my leathers (AStars Atem one piece). People with normal-sized calves will probably not have this problem. No issues with the plastic shin protectors on the tops of the boots fitting around my enormous calves, even in leathers.
Really nice quality and good looking boots, and excellent price!

Haven’t had a chance to ride in them yet but the fit when wearing them around the house is way more comfortable than the Sidi boots I had before, alit more room in the toe box. And as always STG is a great site to buy from.

if you’re wondering about sizing to give you an range i wear 11 - 11.5 in all my shoes, ordered an 9.5 for the boots and the boots fit just like an 11-11.5 so watch the video and STG explains sizing very well. i would recommend these to all riders. Great boots, very comfortable and they grip very well to the pegs so you don’t have to worry about slipping off in corners.
