    Shimano MT33 shoes, what size?

    Saw a good deal on Shimano MT33 SPD shoes on Nashbar today, and they actually have larger sizes in stock! I'm wondering what size to get, though.

    I normally wear US size 13 in most regular shoes. My Bontrager MTB shoes say they are size 48, US size 14 inside the shoe itself. My Stem/Lems minimalist shoes I wear at work say 46/13 inside them.

    One of the Amazon reviewers said they wear 11.5 and the 46 was too snug, but the 47 was better. So I guess I would need a 48?? Luckily Nashbar says that size is in stock. But I hope I can return if they don't work out well.

    Really hard to know without trying them on...do they have free returns? can you go somewhere to try them on?

    I have a similar pair of shoes, but can't remember what model. I normally where a size US 12, but my foot is really more of a 11.5 but I need a wider toe box for my foot so most 11.5 shoes are to tight to be comfortable.

    I THOUGHT I got a 45 in my similar shoes, not a 46 (but I could be wrong). they fit snug, but I wanted a snug fit so my foot didn't move around in them at all.

    I think other bike shoes include a size 45, 46, but not positive. I am pretty sure the last pair of shoes I got, a mountain shoe, was 45 and fit well.

    If it helps I can try to look at my shoes when I get home to confirm what sizes I have.

    I think that many bike shoes are designed to fit snug so will feel tighter then a normal shoe in the same size. Its personal preference if you like this fit or want to go a size up.

    Just pulled the trigger on the 48's (largest size they had). Hope they work out okay. I'm sick of my super-stiff MTB shoes, which basically feel like road shoes with large plastic pieces on the bottom to keep the SPD cleat from sticking out.

    The MT33's have very good reviews both on Nashbar and Amazon.

    I have a pair of those. The cleat nut-plate came already installed. No pulling the insole and doing it yourself, ready to go. TSL had mentioned that cold is transmitted through the cleat into the shoe so I decided to see if I could do a Southern Climate modification.

    The classic good ol' boy redneck method worked. Duct tape, Alabama Chrome!!

    When I got the insoles out I found that there was nothing over the cleat-nut recess like on my road shoes. The unused pair of screw holes went straight through to the inside of the shoe. No wonder my toe covers weren't worth a hoot!!! A strip a duct tape gave me a lot more warmth, like closing a window.

    Nothing bad about the shoe.....I really like them. Not too bad to walk in, they are stiff but the sole is shaped so they kinda roll along. They have a big boxy toe--room for extra socks without that cramped feeling. They are quite heavy compared to my road shoes.

    Tuck the laces in on the right shoe.

    Nice, hope the toe box is big enough on these ones I just got. I hate wearing shoes in general, especially any that constrict my feet (my minimalist shoes are extremely roomy, feel WAY better than Vibram Five Fingers). My MTB shoes are narrow such that more than 1 pair of socks constricts my toes and makes them feel even colder, even with covers.

    only when you buy the second pair of the same thing, can you predict what size some shoe will be


    thats why you put your foot into a shoe first, then Buy it , in person.

    I got a similar but different model that had a velcro strap...great for tucking the show lace in

    I had to install my cleats myself. The ones I got came with a sticker to put inside to do the same thing as your duct tape, though I assume duct tape would be a bit more effective.

    I have always had to put the cleat nut plate in also. These were new when I got them so I just figured that the sticker was already on. All I did was screw the cleats on. Couldn't see daylight through the screw holes with the insoles in place.

    I've had them for three seasons and they are great. Minor changes:

    1) CT Yankee redneck mod with duct tape as described above. That, wind booties and wool socks have been fine in truly crappy weather
    2) A little Loctite on the cleat screws - for some reason they kept coming loose, and I was leery of stripping it by making them too tight Just make sure you get the one that can unscrew

    Also, if you walk a lot in them crap can get in the cleat area. A quick bang together usually gets most of it out. I keep putting off "true" road shoes because these are so damn comfortable and easy to use for road, MTB and spin.

    Yes I normally do that. Have never bought shoes online before, ever. But there are no local places that carry this one. My LBS has a similar style Bontrager shoe for about $90 that I was going to get later, but for $45 for these Shimano shoes yesterday on Nashbar it was hard to pass up.

    Got the shoes today and unfortunately I'm thinking they'll have to go back. They say EU 48 / US 12.3 and I normally wear US 13's. The length is okay, but they seem quite narrow. Even with the laces loosened up it feels like they're putting pressure on that joint between the metatarsal bones and the phalanges, on each side of the foot (1st an 5th bones). Reminds me of the Nike shoes I chucked when I started going barefoot all the time. I used to have narrow feet but maybe the barefooting has made them wider, I don't know. I just wore them at my desk for maybe 10-15 minutes and then was like AHHHHH when I pulled them off, much more so than the MTB shoes I've been using.

    Sucks. Guess I'll try out the similar Bontrager shoes at the LBS even though they're twice as much as what I paid for these.

    Sidi has a Mega series that serves the wider footed folks ,

    but being still made in Italy they are definitely not cheap .

    Well I've worn them around a little bit and they may be okay. Aren't there some kind of inserts I can put in there to stretch them a bit wider?

    I think I will at least try on the ones at the LBS before I decide to send these back or not.

    I have leather Shimano shoes, don't remember the model. They were a bit too snug initially, but the guy at Performance Bike said the leather would stretch, and it did .. took some time and a lot of sweaty riding I wore them without socks for some time .. See if that helps? Are the shoes made of a material that will stretch and break in? Also, don't count on wearing them the whole day, keep a change at work.

    Oh no I definitely won't be wearing them all day. They're much stiffer than I expected, but still easier to walk in (and less noisy) than my plastic-bottomed MTB shoes.

    Yeah I couldn't think of the name. But actually what I think I need is a shoe stretcher. A shoe tree is simply for maintaining the shape of the shoes. I remember my dad and grandfather using them.

    I need these:
