I spotted the adidas Terrex Boost at Outdoor Retailer as as Boost fan knew I had to learn more and try them. The adidas Terrex Boost is in the Spring 2015 (release date) a 11.5 oz 325 gram 6mm drop mountain/trail running shoe. Women's weighs 9.9 oz 280 grams. Retail $160. (Updated: confirmed production weight is 11.5 oz,)
I titled this review Trail Monster as on first sight this is one beefy shoe. Huge lugs,

a substantial upper with overlays along the rand and toe, a shoe clearly design for rough trails, rocks, mud. The question in my mind was what would Boost, the TPU based high rebound midsole that I like so much in the adios boost racer on both roads and yes trails (
review here), add to a dedicated trail shoe? I say adios Boost as close as I can tell the white Boost layer in the Terrex looks identical to the adios, at least in the forefoot and appears to sit on top of EVA that wraps up the sides. The orange Terrex and Boost logoed areas seen around the heel are a TPU based film (same material but thicker than the seamless overlays now seen so frequently on run shoes) support element. It wraps all the way around the heel. The orange TPU is not hard plastic but have some give when pressed and when running, clever.

The speed laces are not my favorite way to keep a shoe snug and just right but clearly adidas has done some homework on these. Lots of friction when tightening, good. We'll see as cord wears if the friction stays. To lock, no goofy additional sliding piece as on for example the Hokas. A small black center button that as one holds the cincher is depressed. Takes considerable appropriate pressure to make it work. Cord is snug and slip free through the cincher, at least so far on new shoes.

The lace tucks into a loop near the toes, no lace garage and a bit worried they might catch on branches or rocks if not wrapped around the lace loops.
The fit is roomy enough for my narrow foot with a substantial enough upper to prevent rolling of the fore and midfoot. It is quite narrow in the forefoot, especially in the area of the last quick lace loop and overlays. Strangely there is no heel counter, just soft leather like material with the heel sitting about half an inch down into the orange TPU collar. Didn't miss the heel counter except a bit on steep uphills when balancing on rocks. The TPU rear and outsole were plenty stable on downhills without the heel counter. The upper does not appear to be "water proof" or "weather resistant", and that's the way I like my uppers even in winter with the laminated rand (just above midsole) overlays protecting from shallow puddles. With the exception of the 3 stripe midfoot bands and the overlays all the way around the outside where midsole meets upper there are no seams or overlays whatsoever over the top of the foot all the way to the front. A very sock like fit using a rugged not overly heavy mesh, a good approach that felt great on the foot if a bit narrow upfront.
How do they run?
Apart from being heavier than I would liked my 7 mile run on a combination of rough, rocky rooty trails and smoother single track was confident, often an issue for this timid older runner on rough terrain. Yes, they ran a lot like the adios boost especially upfront, with a snappy toe spring just like the adios. They were very stable on the rough terrain, smooth and quick on the smoother gravel. Never noticed the lugs. I ran a small amount of pavement and while somewhat slappy noisy the Boost layer seemed to absorb the usual awkward presence of big lugs when running roads in such shoes. Will have to try more road miles to really confirm.
What will they be good for?
I plan to make these my winter foul weather snow running shoe. Boost has the characteristic of being less susceptible to changes in the cushioning in heat and cold so on a cold snowy day on the road the ride should be great.
Apart from winter these should make great mud running shoes and appear to be designed to be a competitor to the Salomon SpeedCross and FellRaiser among others. And I imagine they are also sensational on wet rock given the Continental rubber outsole and the big lugs. While not an ultra runner I imagine we'll see these on the feet of many Ultra folks come next year. For me they will be an everyday trail shoe, ready for just about anything along the way.
Those with wide feet or bunion problems may find the toe box too tight given the overlays.
Despite appearances Terrex Boost certainly can Dance!
