For me, the outsoles are where adidas typically shines in terms of trail shoe construction. Their use of Continental rubber, their own Traxion, and adiwear produces outsole compounds that work really well in many conditions. One other attribute of note concerning adidas鈥?outsoles is the amount of float, or sliding, that they allow dry Adidas Springblade Pro Synthetic Running Shoes trails while still being quite lugged. Many lugged trail shoes don鈥檛 produce this effect and instead have a much more 鈥渟ticky鈥?feeling that really takes a lot of energy out of the legs on long, hardpack downhills. Both the Riot 6 and Raven 3 outsoles are examples of these good qualities that are usually present in adidas鈥?trail outsoles (including the forthcoming Boost models).
Both models are very effective on a variety of terrains and conditions. The main differences are that the Riot 6 has a softer rubber that is much sticker on rocks, and is actually one of the stickiest outsoles I鈥檝e ever used, even when compared to shoes like the La Sportiva X-Country and Mutant which use approach (rock climbing) shoe rubber. The Raven 3 outsole is not as sticky, but plenty adequate for almost any trail condition. Its best feature is the 鈥渁daptive traxion鈥?component, which includes the yellow circular lugs that are designed in such a way as to depress at a much lower pressure than a traditional lug. The result is that the shoe runs really well on hard and smooth surfaces, and yet is still effective on loose terrain and off-trail. It feels stable at all times. Hard to pick a winner in this category as they are both very good outsoles with very different characteristics, but I might give a slight edge to the Riot 6 due to how fantastically sticky the rubber is while still allowing float on hardpack.
