Item # SID003H

There's a reason you see so many Sidis on the trail.

Mountain bike shoes are often flash-free. In other words, you typically find lots of matte finishes in hues that either hide dirt or that look dirty to begin with. Sidi's Spider SRS Vernice Shoes bring some style back to off-road bootery.

The first thing that you'll notice is the high-gloss Vernice (ver-NI-chay) finish on the majority of the new Technomicro microfiber leather. It looks beautiful clean. It looks beautiful dirty. Basically, it develops more personality as you use them.

Your feet are held in place, first, by Sidi's stiff heel cup. Moving towards the upper, retention is ensured through Sidi's Soft Instep Closure System buckle across the top of the foot, and two proprietary High Security hook-and-loop straps across the middle of your foot. Underneath the straps is a thinly padded tongue that has just enough cushion to prevent your foot from feeling too much pressure, while its thin enough to prevent your foot from moving around. This setup is Sidi's time-honored, proven, adjust-on-the-fly, lock-down system for keeping feet in place. Not only does it work flawlessly, but it helps the shoes last, last, and last. However, if you find a way to break them, the buckles and straps are all replaceable.

At the outsole, you'll find a newly designed Carbon Composite SRS Sole that mimics the venerable Dragon SRS outsole. And just like on the Dragon, the toes are threaded for spikes (sold separately — all the threading for toe spikes are the same). The sole is plenty stiff for riding, but not so stiff that you can't scramble in them with a bike on your back. After that, there are big differences. The rubber lugs are softer than those on the Dragon and D5, so they grip rock better in both wet and dry conditions. And because they're softer, they wear a bit more quickly, but wearing down the lugs isn't an issue because they're bolted onto the sole as part of Sidi's Sole Replacement System (SRS). Sidi has also added a rubber toe guard in front for greater durability.

The Sidi Spider SRS Shoes are available in the color Technomicro Black Vernice and in odd and even sizes from 40.0 to 48.0

Second pair of Sidi MTB/Cross shoes

  • Familiarity:I've put it through the wringer

my last pair of Sidi shoes lasted me over 15 years, with replacement parts and a solid sole I was very happy with my old ones. When I finally was willing to invest (yes these are expensive, but they last) in new shoes, I wanted to go with Sidi again. I have worn these consistently for off road riding this year. They fit better than my old ones and I love the carbon sole. I paired these with my Crank Bros pedals (using the protection plate) and I'm very happy.

I went with another pair of size 44 shoes and I believe they fit true to size. Let me know if you have any questions and I'll do my best to answer them.

I wear an older Sidi model for gravel racing but they don't flex enough for comfort when carrying the bike. (After 3+ miles of carrying in this year's Dirty Kanza, my feet were hurting.). How much flex would you say these soles have? Do they work for long, rocky carries?

I do run in them and climb a bit (maybe 100 yards), but I would not think they would be good or comfortable for a 3+ mile carry. Sorry for the late reply, I just saw the comment and question.


Sidi SRS mtb shoe

  • Familiarity:I've put it through the wringer

Comfortable, reliable, bright red visible shoe with replaceable soles, reason i purchased. Bought these earlier this year and love the way they catch onto grassy surfaces uneven pavement and even sand. Quick adjustment straps are becoming the standard. Rubberized toe cover also quite helpful during those inadvertent snags and taps onto pavement, trees, walls, very comfortable shoe.

What size (u.s. mens) do you wear?

Fantastic shoe for Mtn Biking or CX!

  • Familiarity:I've put it through the wringer

I'm almost ready to replace the treads for a second time on these shoes if that tells you the extent of my usage (I've been using them for close to 4 years).

Bought these specifically for cyclocross in the Pacific Northwest and they were perfect for it. Haven't been racing cross so much and now live in Richmond, VA but they have been fantastic for local mtn biking and even better up in the Appalachians where there are some steep enough climbs that force you to do a little hiking.

Flexible enough to be comfortable for running over barriers or climbing steep grades but stiff enough where it counts that you don't feel like you are loosing power on the pedals. Great buckle system makes life easy when you're hands are frozen and you need to make a slight adjustment during a ride or after the ride when you just want to get out your shoes. Not built as a cold weather shoe, but with some merino wool socks, your feet will stay long warm enough for a cold, wet 45-60 minute CX race.

The rubber toe covers are a great touch and probably have helped kept my shoes lasting this long.

Solid - gonna get me some :)
