Topo MTN Racer 4 Wide Ms - Navy/Orange

TOPO ATHLETIC MTN RACER 4 – HIGH-COVERAGE PERFORMANCE SHOES FOR TECHNICAL TERRAIN

See our entire range from Topo Athletic here!

Topo MTN Racer 4 Wide Ms is a versatile and well-cushioned men's trail shoe, designed for technical trails, long runs and competitions. The Wide version features a wide 2E last that provides extra space throughout the shoe, while Topo's anatomical toe box allows the toes to spread naturally.

The fourth generation combines a responsive ZipFoam™ midsole with durable Vibram® Megagrip traction. An updated upper, improved heel construction, and more secure midfoot lockout provide the control you need when the terrain gets rough and technical.

Wide 2E fit with anatomical toe box

Topo Athletic is known for its roomy, foot-shaped toe box. The wide men's version uses a 2E last that provides more room than the standard model - a great option for runners with wide feet or who need extra volume across the midfoot.

The toes are allowed to work naturally for better balance and stability, while the upper holds the heel and midfoot in place. The result is a fit that combines freedom of movement in the forefoot with confident control in technical terrain.

ZipFoam™ for cushioning and responsiveness

The ZipFoam™ midsole provides a balanced combination of cushioning, protection and energy return. The sole height is 33 mm under the heel and 28 mm under the forefoot, giving a 5 mm drop.

The relatively high cushioning makes the MTN Racer 4 comfortable during long training sessions and ultra races, while the responsive feel is suitable when the pace increases. The shoe lacks a rock plate, but the midsole height and outsole construction still provide a protective layer between the foot and the ground.

Vibram® Megagrip for technical trails

The Vibram® Megagrip outsole provides reliable grip and high durability on demanding surfaces. It performs well on rocks, roots, gravel and loose forest paths, and provides control in both dry and wet conditions.

The combination of grip, cushioning and a stable platform makes the shoe useful for everything from daily trail training to longer mountain runs and technical ultra-distances.

FKT insole with fast water drainage

The new FKT insole is made of beaded foam cells that absorb some water and help the shoe drain faster after passages through streams, wet grass and mud. The material also provides a softer step-in feel and extra responsiveness underfoot.

An improved gaiter attachment system helps keep gravel, needles and other debris out of the shoe. The MTN Racer 4 is compatible with the Topo Athletic Switchback Gaiter, sold separately.

Fit and size

The Topo MTN Racer 4 Wide Ms has a wide 2E fit and is suitable for runners who need more room than Topo's standard last. The Wide model is also designed to keep the midfoot and heel stable, while the toe box provides plenty of room for natural toe spread.

The model is generally perceived as normal in length. Choose your usual running shoe size as a starting point. If you are between sizes, run very long distances or want extra room for swollen feet, the larger size is recommended.

Care instructions

Brush off loose dirt after use and clean the shoes by hand with lukewarm water, a soft brush and mild detergent. Remove the insoles and untie the laces for easier cleaning and drying. Do not machine wash or tumble dry the shoes. Allow them to air dry at room temperature and avoid radiators, drying cabinets and other direct heat sources.

The Topo MTN Racer 4 Wide is a men's trail running shoe with extra width across the toe box, midfoot and heel. The model combines Topo's anatomically spacious toe box with a more enveloping fit around the midfoot and heel.

The Wide version is suitable for those who need more space than Topo's already relatively spacious standard last offers.

Size chart

The size conversion is the same for the standard and wide versions. Wide affects the width and volume of the shoe, not its stated length.

Topo states that CM measurements are based on the insole measurements, so measure your foot and leave extra room in front of your toes.

How is the Topo MTN Racer 4 Wide sized?

The MTN Racer 4 is generally considered to be a normal length. The upper in the fourth version sits slightly tighter over the midfoot than some previous Topo models to provide better control in technical terrain.

The Wide version has approximately the following width:

• Toe box: 2E
• Midfoot and heel: E
• Difference from standard: approximately 3 mm extra width

The standard version of Topos already has an anatomically wide toe box. Wide is therefore mainly recommended when the standard version presses on the forefoot or midfoot – not just because you want a lot of room around the toes.

User size perception

Most users find the MTN Racer 4 to be normal in length, but opinions on the width vary more. Runners with wide forefeet generally appreciate the toe room, while some find the Wide version to be too roomy and allow the foot to move around in the shoe.

There are also users who find the model to be slightly shorter or less roomy across the midfoot than other wide Topo models. If you are between sizes, or have long toes, a half size larger is often the safer choice.

Our size recommendation

• Normally choose the same US size as in other Topo models.
• If you are between two sizes, we recommend the larger one.
• Go up half a size if your toes are close to the front edge of the shoe.
• Keep your regular size but choose Wide if the length is right and the standard shoe presses on the sides of the foot.
• Don't choose Wide to compensate for a shoe that is too short - go up a size.
• The standard version is usually better if you have a narrow or normal-width midfoot and heel.
• Wide is best suited for wide forefoot, higher foot volume or pressure over the midfoot.
• When running long trail runs, you should take into account that your feet may swell.

How to measure your foot

Measure both feet in the afternoon or evening, when they are normally at their largest. Wear the running socks you plan to wear with your shoes.

1. Place a piece of paper with the short side against a wall.
2. Place your heel lightly against the wall with your entire body weight on your foot.
3. Mark in front of the longest toe.
4. Measure from the edge of the paper to the mark.
5. Repeat with the other foot, starting from the longer measurement.
6. Add at least 0.5 cm when comparing with Topos CM column.

For long runs or a lot of downhill running, you may need closer to 0.8–1 cm of extra space in front of the longest toe.

Check the fit

The right size and width means that:

• there is approximately 0.8–1 cm of space in front of the longest toe,
• the toes can move and spread without resting against the upper part,
• the forefoot is not compressed from the sides,
• the midfoot is kept stable without painful pressure,
• your heel stays in place when you run uphill,
• the foot does not slide forward or sideways during downhill running,
• the tips of the toes do not hit the front edge of the shoe on downhill slopes.

If the length feels right but your foot moves sideways, the Wide version is probably too wide. If the shoe presses on the forefoot despite being the right length, the Wide is a better choice than going up several sizes.
