Product Information "Dynafit Ultra 100 V3 GTX Men’s Trail Running Shoes"

The men’s Dynafit Ultra 100 V3 GTX was designed for long trail runs and challenging conditions. Thanks to maximum cushioning, a waterproof GORE-TEX® membrane, and a high-traction Vibram® Megagrip outsole, you’ll conquer even long distances in any weather with comfort and confidence.

Dynafit Ultra 100 V3 GTX – maximum comfort on long trails

Whether on forest paths, alpine trails, or challenging mountain hikes—the Ultra 100 V3 GTX offers you reliable support and exceptional comfort. The combination of strong cushioning and a stable sole construction reduces stress on your joints and ensures a secure running experience on a wide variety of terrains.

Waterproof thanks to GORE-TEX®

The integrated GORE-TEX® membrane reliably protects your feet from rain, mud, and moisture. At the same time, the shoe remains breathable and ensures a comfortable foot environment even on long runs.

  • ✓ Waterproof and breathable GORE-TEX® membrane
  • ✓ Vibram® Megagrip outsole for excellent grip
  • ✓ Maximum cushioning for long distances
  • ✓ Maximum Volume Lasts for Superior Comfort
  • ✓ Wide fit in the forefoot area
  • ✓ 6 mm heel-to-toe drop for a natural roll
  • ✓ Ideal for trail running in any weather

Comfort Even on Ultra Runs

With its roomy fit, the shoe offers plenty of space in the forefoot area. This keeps your feet comfortable even on long runs and helps them tire less quickly.

Safe on Any Terrain

The Vibram® Megagrip outsole offers excellent grip on dry and wet trails. The deep tread pattern ensures optimal traction on loose, rocky, or muddy terrain.

What size is right for you?

The centimeter measurement on the shoe box refers to foot length, not sole length. It’s best to measure your foot in the evening while standing and wearing the socks you’ll run in: place your heel against the wall, then measure the distance to your longest toe. For trail running, add 5 to 10 millimeters; otherwise, your toes will hit the front of the shoe when running downhill.

  • √ EU 41 – UK 7.5 – US 9.5 – Foot length 26.5 cm
  • √ EU 42 – UK 8 – US 10 – Foot length 27 cm
  • √ EU 42.5 – UK 8.5 – US 10.5 – Foot length 27.5 cm
  • √ EU 43 – UK 9 – US 11 – Foot length 28 cm
  • √ EU 44 – UK 9.5 – US 11.5 – Foot length 28.5 cm

The Ultra 100 V3 is built on a roomy last with a wide toe box. If you’ve been wearing narrow road running shoes, stick with your usual size in length and you’ll simply gain extra room in the toe box. If you’re unsure, order two sizes and send back the one that doesn’t fit.

What distances is the Ultra 100 V3 GTX suitable for?

The shoe was specially designed for long trail runs, ultratrails, and extended training sessions.

Is the shoe waterproof?

Yes, the GORE-TEX® membrane provides reliable protection against moisture while remaining breathable.

How does the shoe fit?

Thanks to the Maximum Volume last, the Ultra 100 V3 GTX offers a comfortable, slightly wide fit with plenty of room in the forefoot area.

How does the shoe fit?

Normal length, generous width. Dynafit designs the Ultra 100 on a last with plenty of volume, which is comfortable over long distances because your feet swell slightly as the hours go by.

Do I need to go up a size because of the GORE-TEX membrane?

No. The membrane adds hardly any bulk. What’s more important is that there’s enough room in the toe box so your toes don’t hit the front of the shoe during long downhills.

I’m between two sizes—what should I do?

Go with the larger size for trail running. Half a centimeter of space in the toe box will save your toenails on downhill runs, while the shoe still fits snugly thanks to the lacing.
