Ultra 100

I don't know if the Dynafit Ultra 100 has changed in the last couple years. I had a pair 3 years ago, they had the Pomoca outsole. Most of my shoes are pretty minimal, I love Nnormal Kjerags and Merrell Long Sky. The Dynafit felt heavy and unstable to me. I sized up 1/2 size (US), it was still very low volume for the toes. It was a pretty comfortable shoe, but too heavy and slow for smooth trails, too thick and unstable for technical trails.

There are no trail shoes with a pronation-support system. Such system is counterproductive on an uneven trail and can cause problems and injuries. I am running Adrenaline and Glycerine GTS as my road shoes and have x-bionic, dynafit and saucony Peregrines as my trail running shoes. X-bionic and dynafit are relatively stable, I use a special insole in Peregrines (not from orthopedics)

The Dynafit Trail, light, stable great grip and versatile cushioning! [https://www.dynafit.com/it-it/scarpa-trail-running-da-uomo-08-0000064111](https://www.dynafit.com/it-it/scarpa-trail-running-da-uomo-08-0000064111)
