Adidas Terrex Agravic TT — Our Review

A technical terrain weapon that earned its stripes on the trails outside Trondheim.

We put the Agravic TT through its paces on the Ecotrail Trondheim 33K course — a route that starts with a gradual forest climb from Utleirahallen, hits the short sharp spike of Solemsvåttan at 435 metres, then transitions into the flowing coastal trails of Ladestien to the finish. Wide prepared trails, rolling mixed terrain, some early-season ice in the shaded sections — a fair and varied test for a shoe positioning itself as the technical alternative to the Speed Ultra 2.

The Continental Rubber — The Real Story

Let's start where it matters most: the outsole. The Continental rubber on the Agravic TT is genuinely excellent. On the icy patches we hit early in the Solemsvåttan section, on the mixed forest trails, and on the wet coastal paths of Ladestien, grip was consistent and confidence-inspiring throughout. It's the kind of outsole where you stop thinking about your feet and just run — which is exactly what you want. The 4.5mm multidirectional lugs bite without being aggressive enough to slow you down on harder-packed sections.

The Toebox — Know Before You Buy

This is the TT's most significant real-world limitation and worth being upfront about. The toebox is notably narrow — more so than most trail shoes at this price point. If you have a wider forefoot or tend to swell on longer efforts, this will become a problem before the finish line. On a 33K it was manageable, but anyone with wider feet or planning to race longer distances should try before they buy or size up half a size.

The Rocker — Less Than the Speed Ultra 2, and That's a Trade-Off Worth Understanding

Compared to the Speed Ultra 2, the TT has a noticeably less aggressive rocker. In practice that means two things. On technical terrain, varied footing, and mixed trail surfaces — exactly what we ran on around Trondheim — it's a genuine advantage. The shoe feels planted and controlled where the Speed Ultra 2 can feel like it's trying to throw you forward. The wider platform gives you stability on off-camber sections that the narrower Speed Ultra simply can't match.

The trade-off is on the fast, smooth sections. On the prepared trails and Ladestien's runnable coastal stretch — where you want the shoe to help you push and flow — the TT doesn't give you the same propulsion and energy return that the Speed Ultra delivers. It's not a slow shoe, but it's not a rocket either.

The Bottom Line

The Agravic TT is the right shoe for the right terrain. If your racing takes you over mixed, technical, or unpredictable ground — the kind of course where you need to trust your feet and not just your pace — it delivers. The Continental outsole alone justifies serious consideration. But if you run primarily on fast, smooth trails and want a shoe that rewards efficient running with genuine energy return, the Speed Ultra 2 remains the sharper tool.

Best for: Technical and mixed terrain, conservative foot strikers, runners who prioritise stability and grip over propulsion.

Watch out for: The narrow toebox — try it before race day.
