Item # SHI0612


Let's say that after years of road racing, you're attempting your first triathlon. Training for three disciplines is brutal on your body, but it's equally hard on your budget. As a result, you might be tempted to use your ultra-rigid, buckle-secured road shoes for the bike leg of the race. However, before you do, consider the comfort that you'll add, and the seconds that you'll subtract from your time, by investing in the Shimano SH-TR31 Shoes. They're lightweight, lightning-quick to pull on and adjust, and compliant enough to keep your feet fresh for your run without sacrificing any power transfer.

It seems cliché to say that races can be won and lost in the transition stages, but this often proves true. With a large pull tab at the heel and a single strap over the instep, the SH-TR31 is more akin to a slipper than a shoe. Additionally, the fact that the strap secures towards the inside of the foot allows you to hook the shoes up to your bike, jump into them, start pedaling, and then strap up--without having the strap crash into the spinning crankarms. Resist the temptation to scoff -- with practice, these are easy seconds to gain on the competition, and easy seconds are hard to come by over the course of countless kilometers of suffering.

Shimano gave the TR31 shoes its normal last (or shape), ensuring that the fit is snug to reduce the possibility of hot spots. And the lightweight, fiberglass-reinforced polyamide sole transfers power to the pedals, without being so rigid that it causes numbness and discomfort that can escalate into serious pain when you start running. The upper of the TR31 is made of tough, stretch-resistant synthetic leather, and generous moisture-control mesh inserts provide plenty of breathability for hot summer days. Plush, seamless fabric lines the inside of the shoe to ensure sock-free comfort.

The Shimano SH-TR31 Shoes are compatible with three-bolt cleat designs, as well as two-bolt SPD pedals when paired with Shimano's SM-SH40 adapter. They come in whole sizes from 36-52 and in the color White/black.

Decent, Entry Level Tri Shoe

  • Familiarity:I've used it several times
  • Fit:True to size

These were the first Tri shoes I bought and they do the job, but I am sure there are better ones out there. If you don't know what you want in a Tri shoe but you are looking for something decent that you can wear barefoot and that is lightweight and decently drains - then it's a good shoe. I would imagine higher end shoes have a more contoured fit. I am a size 10 with a double EE width. I bought my typical euro size 43 but felt they were a little small which I chalk up to the width issue. All that said, I used them about 20 times now and they work well enough that I'll wear them out to the end.


Good start

  • Familiarity:I've put it through the wringer

These are great entry level tri shoes. Zac is correct in that if that toe smashed, it kind of stays that way..... permanently. The pull tab is made to be cut to length, very comfortable and a good all around value for what you get. I would almost suggest buying a half size smaller than listed as they seemed to soften and stretch after a couple rides. This is the case for me going barefoot now. Like said above, not the best, not the worst, but a good start.


Great Shoe

    My only complant on the shoe and its not the shoes fault I had thrown in the truck for a week or so and the toe was smashed down and it makes it nearly impossible to get out. Great Tri Shoe and great road shoe for me.

    I have very high insteps & most shoes do not fit correctly .. I do a lot of road riding & these shoes work the best . cool in the summer & also work well in the winter with heavy socks
