Tougher than nature.

Shimano designed the SH-AM45 Mountain Bike Shoe so you could tackle a trail without the trail tackling you. The AM45 is built with a raised outsole that wraps around tough synthetic leather to offer added protection for rough sections of trail. The mid-top design protects your ankle while the no-mesh design keeps dirt and rocks out. A specially designed ultra-grip outsole stands up to trail debris and keeps you from landing on your butt when you get off your bike, and the fiberglass-reinforced polyamide soleplate transfers power directly from your foot to the pedal. SPD compatibility allows you to clip in for more tolerable pedaling sections. 

  • Synthetic leather, no mesh uppers

Be careful on long rides

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I bonked on a long, flat ride recently after getting lost and not having enough food for the extra, unintended miles. As I starved, my feet started hurting very badly. I stopped, took off these shoes and rubbed my feet as I begged passing riders for food. No one stopped. I was 20 miles from the staging area! Five more miles and my feet are screaming. Repeat rubbing, begging for naught. Repeat twice more. Feet needed amputation after 40 miles. Finally, a guy on a crappy 80's rigid fork with a handlebar basket out of the Wizard of Oz saw me whimpering 5 miles from the stage - rubbing my feet - and gave me 4 of the most delicious tangerines created my God. These shoes are great for 8 mile loops in cold weather. You will pay a pain price at 20 plus miles.

Too bulky

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: 43

I've only used them once (and I'm returning them). They are too bulky and slope towards the front, so they slide off the pedal binders (I did not try them with SPDs).

Great shoes

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 44

They are a little bit heavy but it's not a game stopper. When mine wear out I will buy a new pair.

Awesome shoe.

The only thing I was worried about with these shoes was them being too hot in the summer. Well, I can now say that I never had that issue. These shoes did great in the hot weather in St. George and Moab in the middle of summer. I can also say they rock in the winter. I rode this year in these shoes (with Smartwool socks) down to 32 degrees and was never cold. My only complaint is that around the top of the shoe there is a cotton type faberic over the foam and I ripped it a little while riding at Deer Valley this last summer.

This shoes is a great DH or AM shoe.

I love the total coverage and the ability to clip in.

I wear 39 (size 8 in women’s) and they fit perfect.

They also are very comfortable for any hiking you may encounter.

They are a little heavy and not overly ventilated.

Attached is an amusing photo of these durable shoes still attached to my pedals after a crash in which I became detached from my bike!


Get ready to get rowdy

A great downhill OR trail shoe. It's stiff enough for a relaxing trail ride, but you can push it as hard as you want in any sort of race you like. I wore these when temps got cold during the collegiate race season this year and they kept my tootsies warm enough to not worry about my feet during the race. It's also nice to have a shoe without cleats if you're planning on doing some hike-a-bike action. They do run a bit big, so you may consider sizing down.

Hard To Beat For The Price

    I primarily ride XC and lift-accessed trails around Park City and these shoes have been great for both. They're comfortable, functional (I love the full wrap), look decent enough, and, most importantly, fell in a great price range. A previous reviewer noted that they may run a little hot in the sun which I agree with but haven't had any major issues.

    Hard To Beat For The Price

    I have few pairs of these.

      I prefer clips for DH and XC riding. It seems to be getting a bit more common for DH. How many times I have ridden Whistler and the amount of people who can't comprehend being clipped in. I can't imagine not being clipped in. These are great shoes for DH and XC riding. I wouldn't recommend them for riding flat pedals , they are not nearly as grippy as 5 Tens.

      Great Shoe

      • Familiarity: I've put it through the wringer

      I just got my second pair of these shoes. I love them. The full wrap keeps the water out and the laces clean from mud. The only thing about this shoe is it is warm, on hot desert rides you will really notice this.

      Fantastic Shoe

      • Familiarity: I've put it through the wringer

      Purchased this shoe due to its flat bottom, Mountain biking and an occasional DH ride, and am very pleased with the decision.

      Sizing: I wear size 10 and the 44 is perfect.

      Waterproofness: excellent, water stays out. At the end of a couple of wet rides, everyone else had soaked feet. Also with the cleats attached the shoe worked fine on flat pedals on the downhill bikes.

      With this shoe you are able to pedal without being clipped in, and finding the clip is rather easy due to the flat bottom.

      The shoe grips very well, better than my Giro or Shimano shoes with lug bottoms.

      There is plenty of padding around the shoe and in the tongue. The laces give me a better fit than velcro straps. They are a little heavier, but it is mountain biking. The shoe performs excellent and I will purchase another pair when needed.

      Shimano am45

        Great shoes, but the sizing is a bit weird though. The 37 is a bit too small and the 38 is a bit too big. I wear thick socks when I ride anyway cuz my tootsies are always cold, so I am gonna stick with the 38s.

        Spacey but effective

          At first I felt like these shoes where a little to spacey looking for me, but I have grown to like them. Probably because I have been very satisfied with there performance. Paired with the Shimano PD-M647 SPD Dual Platform Pedals, this setup is a perfect compliment to my freeride rig.

          Small sizes, comfortable

            Thank you Shimano for making a DH SPD shoe in my size! I have the fiveten Karver shoes but my feet still slip in rocky technical sections and fiveten doesn't make a DH/Freeride SPD shoe in my size. I ride clipless for XC and missed that feeling for DH. I wear a size 6/6.5 in women's shoes and ordered the 36 at first. Too small, so I got the 37, just a bit too big but much better fit than the 36 (toes curling). I use these shoes with the Shimano DX clipless pedals which work great together: easy to clip in and out, big comfortable platform.

            good quality shoe

              Strong shoe for MTB, I have a 10 shoe and size 44 is perfect fit. Grips well on the wet stuff. Can take off the cleat and use on flats.

              Great shoes, clipped or unclipped.

                This is my first season using clipless pedals and I ride these with a pair of Shimano 545's. Compared to the skateboard shoes I started off riding with these are worlds better and much stiffer. Before skateboard shoes I rode with regular tennis shoes and slammed my foot into a tree stump, which hurt really bad. The overall protection this shoe offers for unfortunate tree stump encounters is invaluable. As a newcomer to clipless I'm frequently riding sketchy terrain unclipped with these shoes, and find the grip amazingly good even though they are not specifically designed for it. I ride these with flat pedals as well and find them to be a great all-rounder bike shoe. I considered the AM41 but decided that the clipless feature may come in handy for less sketchy terrain and I can work my way up with them, and were a necessity for BMX racing.

                My only gripe is from what others claim, that these are slightly more difficult to clip in/out of than regular bike cleats, but that is understandable given their more recessed clip location.

                nice, but wide + high volume

                  I ordered a 39 and normally wear a 7.5/8 in women's shoes. The stiffness is awesome. I don't have a super skinny foot but these shoes were wide and high volume-- I can only get a good fit by cranking down on the laces, and with them that tight, the hooked velcro on the flap doesn't make contact with the velcro loop strip. If I just casually throw these on, my heel slips when walking/pushing up section of trail Plus these shoes are hot! and I live in the Montana rockies. I may put some superfeet insoles in these to try and take up some space, but may also return and try for the Mavic alpine or alpine xl... or five ten hellcats.

                  Great shoes

                    These are almost perfect. Not too stiff and very comfortable. The only problem I have is the heel pocket. It is a bit large, so when I walk my bike up hills, my heel pulls out. That's a pretty easy fix for the overall quality of the shoe, so I'm not complaining. I love the flap over the laces!
