The golden ratio of triathlon shoes.

We don't have to tell you that triathlon shoes are a whole different ballgame than traditional cycling shoes. And luckily for your feet, Giro already understands the fundamental differences. With Giro's Mele Triathlon Shoes, you receive the ideal blend between comfort and power -- easier said than done.

To achieve this golden ratio, Giro engineered the Mele Triathlon shoes to ride the line between comfort and rigidity. As you've probably experienced, triathlon shoes tend to lean towards one polar extreme or the other. In our experience, we find that most manufacturers develop the outsole as stiff as possible, only to later compensate with the upper design. However, through its partnership with Easton in the development of the Mele's EC70 carbon fiber outsole, Giro was able to integrate both properties, seamlessly. The EC70 outsole features a low stack-height that dramatically reduces weight, while still retaining an impressive level of stiffness. But, if the sole is too stiff, your feet are going to suffer on the running leg of the course. That's where EC70's fiberglass composite comes in. This element of the construction permits just enough flex over the arch to maintain a consistent level of blood flow. Even further along the lines of comfort, Giro and Easton designed the transition point between the outsole and the upper to allow 'spill over.' Instead of wrapping up the corners of the carbon, the Mele greets the ball of the foot with the upper. This means that when your feet either swell or expand, say when you stand on the pedals, the EC70 outsole permits the room for this expansion to occur. So, you can say goodbye to hot spots and one of the most common points of abrasion.

You'll also find that the flow of thoughtful designs carries over to the insole and uppers of the Mele. Starting at the uppers, breathability is the name of the game. Take a look, and you'll see that a majority of the surface area is constructed from air mesh. For the rest of the uppers, Giro used a breathable and durable microfiber. This means that the Mele maintains a consistent airflow over the foot to minimize sweat buildup, and to aid in drying the foot after T1. For the footbed, the Mele benefits from Giro's SuperNatural Fit Kit insole. This features a fully-adjustable arch support system, and to top it off, it's also received an Aegis anti-microbial treatment to keep the funk at bay.

Now, don't think that Giro forgot about one of the most important features of a triathlon shoe -- the point of transition. Giro incorporated a two-strap closure system, mated with a 'burrito-wrap' upper. What does this mean? Well, the Mele features an opening that runs over nearly the entire top of the shoe. The burrito analogy is drawn from the Mele's upper construction where one layer of the upper wraps over the other. This allows you to really dial in the volume of the shoe, whether it be for training or on-the-fly during a race. For your T1 transitions, the two-strap closure system is a breeze. The large top strap opens away from the drivetrain to allow a quick and seamless securing of the shoe. As for the bottom strap, you'll find that this is used less for transitions, and more left alone once you've established your desired volume and fit. However, the gripper tabs placement on the strap simplifies any adjustments that you might need to make from the saddle. To really speed up T1, Giro has also included a durable pull-tab at the heel.

Great shoes

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 43.5

These are great shoes! The sole is thin, light and stiff. They work great without socks. Consistent fit to my Giro road shoes, they come on and off quickly in transition. No slipping, no hot spots. I love them. Hit me up directly with any questions. 801-204-4557

Technically they are men's shoes but are more unisex than anything. great shoes. I love mine. Hit me up directly with any questions. 801-204-4557

Could not go wrong for the price

  • Familiarity: I've put it through the wringer

These shoes seem to always be on sale for $100 or less. I bought a pair for the 2 - 3 triathlons I do each year, mostly motivated by price. I have found these shoes to be light, comfortable, stable, and quick and easy to pull on and off. They actually end up splitting time with my dedicated road shoes, which was not intended.

Suitable for foot binding

    We ordered a full size bigger for my wife since these run small, but these shoes are still 2-3 sizes too small. The size chart on these shoes is a joke.

    • Familiarity: I've used it once or twice and have initial impressions

    I bought these shoes cause they match my tri bike (obsidian & highlight) and because of the price and I was looking to upgrade my shoes. I had been riding in LG Tri Speed shoes, which I have loved, except for the color (white). To compare them to the LG they are a lot lighter, but not as wide as the LG's. I wear an 11-1/2 running shoe and I ended up getting the 46 because of the narrow toe box. I have ridden a few times and I cannot complain, as soon as it warms up I'll try them without socks, which will be the ultimate test.

    are these spd compatible? (indoor spin)

    I don't believe so. You're looking for mountain bike style shoes. Those will allow you to attach the 2-bolt style SPD cleat.

    Great shoe, great fit

    • Familiarity: I've used it several times

    Bought them for both tri and road bike use. Were slightly tight out of the box but after 50 miles or so they adjusted to my foot shape and have maintained that since. Great in climbs and rolling hills and have good breathability. Amazing price for such a great shoe, get a pair before they are all gone!

    Cheap-looking, klunky-looking shoe

    • Familiarity: I returned this product before using it

    These fit well but looked and felt cheap and plastic-y, with an ugly rounded toe box, an unappealing white "patent leather"-style upper and an EC70 sole that looked more like polycarbonate or composite than like carbon. The toe and heel counters (or whatever those little pads on the sole are called) were thin and apparently vinyl, not rubber, and would've been slippery: not at all what you need in a road or triathlon shoe.

    Good thing your tri results aren't based on looks then. These shoes are great and do exactly what they are suppose to, light and sturdy, breathable and easy to transition into and out of....sounds like a solid tri shoe to me.

    Great shoe, great price.

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

    This is truly a great shoe. I ride 100-200 miles a week. I wouldn't expect anything less from Giro. I had a pair of Bont Sub 8s, but I like these Giros much better. The shoes offers a larger toe box, nicer insoles (which come with 3 different inserts) and look to be very well constructed. They are fast to get on in transition, and are great with or without socks. I wear them for both, long course and short course triathlon, along with all of the group rides and road training I do. I would recommend these to anyone to try.
