I have been running in Agravic 3 and Agravic GTX since October and was looking for an longer distance shoe for technical trails. I was looking forward to the TT release as it promised to be just that. However, my experience with them does not prove this. I often see people say they are more stable than the Speed Ultra, and perhaps so. I have never used the Ultras so I cannot compare. But I will say that the TT is far from being more stable than the Agravic 3. Running in the TT on technical trails with roots and rocks resulted in constant ankle rolling. These are the same trails I always I ran in the Agravic 3 without issue. I did get blistering on both big toes due to the abrasive material and shape of the toe box, but that can be fixed with thicker socks and a little tape if need be. But still a concern. It’s unfortunate as these shoes are super comfortable and very well built. But I fail to see the TT side of it. I’ll keep using them on flat terrain miles just to get my money out of them, but that’s where it will end.

great on trails. .
