Great boots Very happy with these boots. The fit on my size 11's is great - roomy in the toe box and with the lace-up system they snug right up without feeling tight. The lining is very soft on the front of the ankle and the whole boot is really comfortable on the bike. I'm recovering from a foot injury (sesamoiditis) and these boots are a big step up in comfort from my old riding boots. The sole is rigid enough to prevent excessive pressure in the arch of my foot but they're also flexible enough to not hinder operating the controls. I'm very impressed with these boots and glad to have spent the money - they're well worth it. July 28, 2014
Great boot I commute in these boots and wear them off the bike as well. Although I have no plans to go to the track any time soon, I still want a lot of protection on the street. Perhaps a bit overkill for commuting, protective gear is very cheap insurance in comparison to the pain, lost time, and medical costs from an injury. I have not tested the Gore-Tex in a significant downpour but I have stayed dry in a few drizzly days. I am impressed at how much the Gore-Tex allows my feet to breathe preventing sweaty clamminess, even when off the bike. I don't notice significant airflow as one might expect in a heavily vented boot but there is enough to keep me perfectly comfortable. These boots are also quite comfortable while walking around. I imagine these are as close to tennis shoe level comfort that you can get in a track boot. However, I plan on changing into street shoes from now on as the boot sole is not made for extended walking and is starting to show some wear. I got the squeak after walking around for a day but a few drops of silicone spray seems to have fixed that. The speed lacing system is easy to use and provides a glove-like fit. I have not had any problems with the laces cutting through the eyelets in the liner, but I don't pull very hard on the laces. You don't need much to snug them up so it shouldn't be a problem unless you're yanking on them. I originally purchased the Dainese TRQ-Tour Gore-Tex boots and did not care for them at all. The footbed was uniform but too snug for me. However, from the ankle up, the boot was very loose and the top of the boot dug into my shin. Having a background in podiatry I cannot see how the TRQ-Tour would provide any meaningful ankle joint protection. The SMX Plus boots are comfortable, appear to provide great protection, and are race stylish. The only downside is the price but then again, it's a lot less than foot surgery. May 28, 2014
Perfect boot for protection, comfort, and waterproofness If you want a comfortable boot you can hike around in but want great protection this is it. Add on that the gortex breathes so no sweaty feet and it stays waterproof. I love these boots. Mine have been tested in heat and cold and in pouring rain. They run just a size big. I'm a 42 normally and got a 41 in these. Revzilla allows returns so get 2 sizes and return what doesn't fit. BMW R1200R September 13, 2013
Usual excellent quality from A'Stars Love the "custom" fit that the speed lace system provides. The boots have a good feel for the pegs without letting them dig into your feet. These replaced a set of SIDI Vertigo Rain boots that didn't provide enough room to move my toes up and down, thus causing some discomfort, and didn't hold my foot in place because the ankle area was too loose.

Boot fits well. Boot fits very well. A bit snug near the front of the foot, however I do have quite wide feet. Bought these boots in the winter so have yet to try them. They look great and am looking forward to giving them a go through the mountains. January 14, 2013

Ryan K: Well, I've only ever owned alpinestar boots so I can't venture an opinion on the others. I ride a triumph daytona 675.

The SMX plus are absolutely fantastic. They fit great and and offer great protection. Also, in the rain they are guaranteed to keep your feet dry. I've ridden through a couple of rainstorms since I got them and they were true to their word.

I have no track near me but I do get out to the mountains a couple times a year to rip hard. The boots are easy to move around in and I am confident in their protection. They are built very sturdy.

My feet never got uncomfortable while walking or while riding long stints.

I highly recommend these boots to you sir. Hope I was able to help.

Paul H: I replaced a pair of SIDI's that fit kinda funky and like these much better. I've owned several pair of SIDIs and A-Stars and these are the most comfortable. I like the inner speed lace set up and they are definitely waterproof. Nov 13, 2013

Paula C: Hi Patrick,
They sent me your question as a recent purchaser of this boot. I have no idea if they changed the boot for 2013 but I can tell you its a great boot. After riding the Alps in the rain in another waterproof boot that failed; I came back and got these. I just returned from another rainy trip and these worked great. Comfortable enough to hike around in without sweaty hot feet, then very waterproof in the rain. They have tons of protection without being too stiff. The lace up liner makes the fit perfect. I'm a female rider but these men's boots are more protective than women's.

A shopper asked: Hi! I have the SMX-5 waterproof boots at the moment. Are the sizes of those two boots (SMX-5 and SMX-5plus) compareable? I tried on the SMX-5 plus in 40 in the shop but nobody stocks the waterproof version and from memory the waterproof boots seemed to be a bit more tide.

Solon C: The waterproof boots are slightly tighter than the non-waterproof SMX-5s. When I tried the waterproof ones on in a store I had to go one size larger. With that said however, keep in mind that overtime when the padding gets broken in the boot will feel LESS snug, kind of like how a new running shoe feels initially versus one that has been actively worn or a while.

A shopper asked: If it is the same boot as the regular SM-X plug a Gore-Tex membrane, is the main zipper waterproof? Dec 18, 2012

RevZilla: The Alpinestars S-MX Plus Gore-Tex Boots have fixed internal booties that contain the Gore-Tex membranes. The booties go as high up as the zippers. The zippers are not water proof but the internal booties are. Dec 18, 2012
