Bottom line

The Reebok All Terrain Thunder 2.0 is the all-terrain trail running shoe that offers a very reliable shoe to get you through obstacle races in the wild and the muddy grounds. Its tread and sole are intended to allow safe and easy running on wet or tough trails, but they make the shoe heavy. Although it is a bit wider, it makes a great running buddy on the wild areas. Because of the All Terrain Thunder 2.0’s performance and quality, it is a shoe that is well worth the stiff price tag.

78 / 100 based on 8 expert reviews

  • 80 / 100 | New England Spahtens | Level 2 expert

    These are considerably less minimal than prior All Terrain models.

  • 83 / 100 | Reach Your Peak | Level 1 expert

    It is not light, but it is sturdy and the perfect shoe for mud runs.

  • 71 / 100 | Obstacle Racing Media | | Level 3 expert

    However, there were tongue issues that caused chafing, and they fell apart in short amount of time

  • 100 / 100 | The Mudman Report | Level 2 expert

    I see these being a good option for flat and fast shorter races, and of course for trail run training.

  • 80 / 100 | On My Way To Sparta | | Level 2 expert

    If you are okay with a 12 mm heel drop and want a comfy shoe to go trail running, then you could be very happy with the Reebok All Terrain Thunder.

  • 50 / 100 | Obstacle Racing Media | | Level 2 expert

    Even though, these became my “walk around” shoes, they began to fall apart after a few months.

  • Reebok gives the 2nd installment of the All Terrain Thunder a serious makeover. It is clearly more cushioned than the original version now that it offers the FoamFusion cushion, which will make runs over the toughest terrain and most difficult OCRs smoother.
  • The traditional laces are replaced by speed laces called the Lock and Load by Reebok. This is made of a much tougher cord and can be single-handedly pulled for quick and effortless cinching.
  • Working with the laces and the forefoot is a sort of plastic material that keeps off trail debris. Reebok uses the term DirtShield for this very new feature.
  • The lugs are very slightly less aggressive and with much better density to hold on to loose rocks. This update gives the shoe added traction on slippery-man made surfaces designed for obstacle racing as well.
  • Issues of upper durability are adequately answered in the All Terrain Thunder 2.0 in the form of a super-improved Terrain Skin that is made of Kevlar material. This new feature provides exceptional seamless durability and support to the upper.

The fit and sizing of the latest version resemble that of the original. It is quite spacious from the heel to the forefoot that runners would have no problem wearing thick socks. Most runners will surely be able to find their comfort zone with this kind of standard measurement. Available widths are D and B for the men’s and women’s version. Sizing options are 6 to 15 for the men’s and 4 to 12 for the women’s

A slightly aggressive set of trail lugs offer premium traction still. The lugs are facing opposite directions for proven grip, even when going downhill or up a steep incline. They are deep enough to work very well, even when tackling mud. This shoe performs aggressively on trails like the Salomon Speedcross 5.

A decoupled heel isolates shock and helps make transitions a bit smoother. There is also a deep cut running almost the entire length of the shoe for a bit of flexibility and for quicker transitions.

The new FoamFusion midsole gives the Thunder 2.0 a more comfortable and softer cushioning. Reebok delivers the right blend of responsive cushioning by incorporating this new technology with the proven and tested C51 compound.

The upper is a mesh that is sealed and coated with anti-debris features. This is now greatly reinforced by Kevlar type material that really makes the upper stronger without adding any substantial overlays or using stitches. A DirtShield is a sort of plastic/rubber material that sits right near the edges of the eyelets and goes over to the tongue and forefoot. It effectively keeps of debris from entering the shoe. The toe box is made of seamless and sturdy rubber to prevent bruising. Reebok’s very unique hedged H2O Drain technology near the forefoot is one of the best in the business in draining water.
