This is my favorite trail shoe ever! It is has a nylon plate that provides propulsion without the pain. It is light, responsive and works on every terrain.

Stoked on these, great energy return, plush but propulsive, stable but aggressive.

Probably not worth the price tag. Super light and responsive. It might run a little narrow around the pinky toe, but overall it feels quick underfoot. The landing is soft while still giving some ground feel, and you can feel a bit of propulsion as you toe off. I like the updated braided laces, but worry the upper might not offer enough protection for really rugged terrain.

The Cloudultra Pro has become one of my favorite shoes for technical, rocky terrain. I love the nylon plate in this shoe—it does an incredible job protecting the forefoot from sharp rocks and constant trail abuse. When you're out on those "rocks of death" trails where every step makes you question your life choices and fear the pain coming through your shoes, the Cloudultra Pro gives you the confidence to keep moving. The protection is outstanding without making the shoe feel overly stiff, making it a great option for long days in rough terrain.
