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.

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.

A shopper asked:I am riding Naked bike daily (Honda 600 CB600 F Hornet) and sometimes ? ride in a track (Honda 600RR or 1000RR) . I need new boots and ? don't know which boot will be the best choice for me between Sidi Vortice, Alpinestars SMX Plus Gore-Tex and Alpinestars Supertech R? Important things for me are; 1.Protection 2.Daily use comfort while walking 3.Durability (Sidi has replacable parts and in my opinion it is big plus for example) Please helpNov 13, 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.Nov 17, 2013
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. Paula BMW R1200R Suzuki GSXR 750 BMW 700GSSep 13, 2013
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.Jan 21, 2014
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
