The Basics: Getting to Know Our Contenders

Before we jump into the nitty-gritty details, let’s get to know our two star players a bit better.

On Cloudmonster: The New Kid on the Block

On Running, a Swiss company founded in 2010, has been making waves in the running world with its innovative designs. The Cloudmonster is one of their latest offerings, promising maximum cushioning and a unique running experience.

Adidas Ultraboost: The Tried and True Classic

Adidas, a household name in sports gear, introduced the Ultraboost in 2015. Since then, it’s become a favorite among runners and sneaker enthusiasts alike, known for its responsive cushioning and stylish looks.

Comfort and Cushioning

When it comes to running shoes, comfort is king. Let’s see how our contenders stack up in this crucial category.

On Cloudmonster: A Cushy Ride

Imagine running on fluffy clouds – that’s what On aims for with the Cloudmonster. The shoe features oversized CloudTec elements, which are like little pillows under your feet. These “clouds” compress when you land and spring back when you take off, giving you a soft yet responsive feel.

Adidas Ultraboost: Energizing Your Run

The Ultraboost uses Adidas’ famous Boost technology. This special foam is made up of thousands of little energy capsules. When you run, these capsules store and release energy, giving you a bouncy, energized feeling with each step.

The Verdict on Comfort

Both shoes offer top-notch comfort, but in different ways. The Cloudmonster feels more plush and cushioned, while the Ultraboost gives a bouncier, more responsive feel. Your preference will depend on whether you like a softer or springier ride.

Breathability: Keeping Your Feet Cool and Fresh

Nobody likes sweaty, smelly feet after a run. Let’s see how these shoes help keep your feet breathing easy.

On Cloudmonster: Cool and Breezy

The Cloudmonster features a lightweight, breathable mesh upper. This material lets air flow freely around your feet, helping to keep them cool and dry during your run.

Adidas Ultraboost: Primeknit Perfection

Adidas uses its Primeknit technology in the Ultraboost’s upper. This woven fabric is not only super comfy but also allows for excellent airflow. It’s like wearing a cozy, breathable sock.

Breathing Easy

Both shoes do a great job at keeping your feet ventilated. The Cloudmonster’s mesh might feel a tad airier, while the Ultraboost’s Primeknit offers a snugger, sock-like fit with good breathability.

Fit and Stability: Finding Your Perfect Match

A good fit is crucial for preventing blisters and ensuring a stable run. Let’s see how these shoes measure up.

On Cloudmonster: Roomy and Secure

The Cloudmonster offers a roomier fit, especially in the toe box. This can be great for runners with wider feet or those who like a bit more space. The shoe also has a sturdy heel counter that helps keep your foot in place.

Adidas Ultraboost: Snug and Supportive

The Ultraboost is known for its snug, sock-like fit. The Primeknit upper hugs your foot, providing a secure feel. Some runners might find it a bit tight at first, but the material does stretch over time.

Finding Your Fit

If you prefer a roomier feel, especially in the toes, the Cloudmonster might be your best bet. For a snugger, more locked-in fit, the Ultraboost could be the way to go.

Durability: Going the Distance

You want your running shoes to last, right? Let’s check out how these shoes hold up over time.

On Cloudmonster: Built to Last

On Running uses high-quality materials in the Cloudmonster. The CloudTec elements are made of durable rubber, and the upper is reinforced in high-wear areas. Many runners report that these shoes can handle hundreds of miles before showing significant wear.

Adidas Ultraboost: Long-Lasting Legend

The Ultraboost has a reputation for durability. The Boost midsole maintains its cushioning properties for a long time, and the Continental rubber outsole provides excellent wear resistance. The Primeknit upper is also quite durable, though it may show dirt more easily than some other materials.

The Long Haul

Both shoes are built to last, but the Cloudmonster might have a slight edge in terms of maintaining its fresh, out-of-the-box feel for longer. However, the Ultraboost’s tried-and-true design has proven its longevity over the years.

Style and Looks: Turning Heads on Your Run

While performance is key, it’s always nice to look good while you’re working out. Let’s talk style!

On Cloudmonster: Bold and Unique

The Cloudmonster has a distinctive look with its oversized CloudTec elements. It’s a head-turner that screams “high-tech running shoe.” On offers the shoe in a variety of cool color combinations, from subtle to eye-catching.

Adidas Ultraboost: Streetwear Icon

The Ultraboost has become a style icon, worn not just for running but as a fashion statement. Its sleek silhouette and wide range of color options make it a versatile shoe that looks great with workout gear or casual outfits.

Style Points

If you want a shoe that stands out and showcases cutting-edge tech, go for the Cloudmonster. If you’re after a more versatile look that transitions easily from running to everyday wear, the Ultraboost might be your pick.

Materials and Quality: What Are You Really Getting?

The materials used in a shoe can make a big difference in how it performs and feels. Let’s break it down.

On Cloudmonster: Innovative Engineering

The Cloudmonster uses a mix of engineered mesh and synthetic overlays for the upper. The midsole is made of On’s Helion superfoam, while the outsole features their CloudTec elements made of durable rubber.

Adidas Ultraboost: Tried and True Tech

The Ultraboost boasts a Primeknit upper, Boost foam midsole, and Continental rubber outsole. These premium materials have been refined over multiple iterations of the shoe.

Material Matters

Both shoes use high-quality materials, but they offer different experiences. The Cloudmonster feels more structured and supportive, while the Ultraboost offers a softer, more flexible feel.

Weight and Flexibility: Light on Your Feet

Nobody wants to feel like they’re running with bricks on their feet. Let’s see how these shoes measure up in terms of weight and flexibility.

On Cloudmonster: Surprisingly Light

Despite its chunky appearance, the Cloudmonster is relatively lightweight for a maximum cushioned shoe. It offers a good balance of flexibility and support, with the CloudTec elements allowing for natural foot movement.

Adidas Ultraboost: Featherlight Feel

The Ultraboost is known for its lightweight feel. The Primeknit upper and Boost midsole contribute to a shoe that feels almost like a part of your foot. It’s highly flexible, allowing for a natural stride.

The Weigh-In

If you’re looking for the lightest possible shoe, the Ultraboost might have a slight edge. However, both shoes offer a good balance of cushioning and weight, so you won’t feel weighed down in either option.

Water Resistance: Splish Splash

While neither shoe is designed to be waterproof, it’s good to know how they handle a bit of moisture.

On Cloudmonster: Decent Water Resistance

The Cloudmonster’s mesh upper does a decent job of repelling light rain or puddle splashes. However, in heavy rain or deep puddles, your feet will likely get wet.

Adidas Ultraboost: Quick to Dry

The Ultraboost’s Primeknit upper isn’t water-resistant, but it does dry quickly if it gets wet. Some versions of the Ultraboost come with a water-repellent coating, which can be helpful in damp conditions.

Rainy Day Running

Neither shoe is ideal for very wet conditions, but both can handle light moisture. If you often run in the rain, you might want to look for specially designed water-resistant running shoes.

The Sole of the Matter

The sole of a running shoe plays a huge role in your comfort and performance. Let’s take a closer look at what’s underfoot.

On Cloudmonster: CloudTec Magic

The Cloudmonster’s sole is where the magic happens. The oversized CloudTec elements provide excellent shock absorption and energy return. The Speedboard, a firm layer between the midsole and upper, helps propel you forward.

Adidas Ultraboost: Boost and Grip

The Ultraboost’s sole combines the responsive Boost midsole with a Continental rubber outsole for excellent traction. The Torsion System in the midfoot provides stability without sacrificing flexibility.

Sole Searching

Both soles offer great cushioning and energy return, but in different ways. The Cloudmonster’s sole feels more structured and supportive, while the Ultraboost’s sole offers a softer, bouncier feel.
