I purchased these first in May. I have been running in Adrenaline GTS shoes for five years on the road and trail, so I was excited about getting these trail version of the Adrenaline series. My first two runs in them were on dirt roads and they performed great. . similar to the GTS. Then I took them to the mountain trails. After two 12 mile runs in Idywild the soles were destroyed. I though that perhaps this was a faulty pair and returned them for another at REI. (Kudos to REI) After 50 miles in the mountains with the new pair the results are the same. See the attached pictures. My opinion is that these shoes are great if you are running on dirt or grass? If there are any rocks on the trail whatsoever the soles will be destroyed in less than 25 miles. As a matter of fact, the soles on my Adrenaline GTS last longer with mountain running than these "trail" shoes. Having said that. The performance, fit, and comfort of the upper are typical of Brooks Adrenaline GTS and the Gore-tex liner works well. If Brooks were to change the sole of these to a Vibram durable sole these would be the best stability trail runners on the market.
I went for a run in the rainy, muddy, and beautiful PNW yesterday, but my feet stayed dry and warm. The ASR GTXs are a little skinnier than the Brooks GTSs, but my wide foot still fits. It took a few runs to get used to them. Ironically they are a little slick on pavement, but super gripy on the trails. I would definitely recommend these shoes if you plan on running in the mud. I still use my GTSs for dry days, because face it, they are way cheaper.
I bought these shoes 2 weeks ago and already half of the lugs have ripped off. I was unimpressed with how waterproof they were and they provided no friction on bare rock. They were well cushioned and comfortable, but unless you're running on smooth gravel trails stay away. Been buying from rei for years and this will be my first use of their excellent return policy.
I had been trail running for a few weeks and began getting blisters all over my toes and feet with my old shoes. I started researching and with the help of the REI salesman decided on these shoes. To my surprise, they have been outstanding. The blisters are gone and my times continue to improve. My feet have never been happier. Highly suggest these shoes.
I bought a pair and walked in town and on dirt trails. After 3 weeks I noticed that the white portions on the right heel were coming detached. I exchanged them for another pair which I took on a 50 mile hike in Georgia. At the end the right shoe had lost a piece of the sole. Again it looked like the bonding betweeen the white and dark rubber had failed. These were, perhaps, the most comfortable shoes I have hiked in and I had no foot issues whatsoever. Its too bad they fall apart
i have had good success with the regular Brooks Adrenaline gtx and was happy to find this trail version of that shoe.The fit was good though i went up a 1/2 size to deal with the steep down hills in trail races. The grip is good and they handled rain well. They are a bit warm with the goretex lining but i was able to use them at 90 degrees.They handled soft moderately rocky trails, gravel roads and even some pavement both for training and racing trail half marathons quite well. The sole showed little wear at about 200 miles then i used them in the Moab trail marathon and that one race destroyed the soles. The soles started to separate and lost pieces and the exposed softer material was shredded. So good shoes for soft surfaces but not rocky trail, especially sandstone.
I figured out I have worn these backpacking for 84 miles this summer, from Utah's desert to Colorado's continental divide. Carrying a pack certainly adds pressure to the shoe. First the good: even though I prefer a more roomy toebox, these did not create blisters...for the first 80 miles. They kept my feet dry (although I never hiked in actual rain). My feet did not get hot. They are nimble Now the bad: after 26 miles on the continental divide last week, the lugs on the right heel finally just fell off, all of them. The entire back of the heel was gone! And I think this is why I got a nasty, deep blister on my heel before I could patch it. I also got blisters on the outside edge of both big toes. So...shoes that cause blisters this bad go in the trash, sigh. (I know REI will warranty them, but I did get good use from them.) With the Gore Tex bootie, these shoes are VERY tight to get on (I wear 8.5). I was willing to put up with it, but it required both hands to get them on, which is a pain, esp. in your tent on a cold morning. Final thought: people routinely complain about how quickly their light hikers and trail runners wear out, and this is understandable, given the high price. However, I've come to accept that a pair of light shoes will wear out each year. If they only last 2 weeks, that's unacceptable, but I got 80 good miles of carrying a 35 lb. pack over rugged trerrain, so I can't complain too much (plus countless miles of just dayhiking).
At 210 pounds these are too soft for me. Like the goretex though.
Very well made. Comfortable and rugged. Good looks.
I had a pair of these years ago and it was the best all around shoe. Didn’t need to purchase an insole for slight arch support. The aggressive tred made them great for around town use after retiring them from running and also made it possible to sort of run in the snow in the winter without slipping everywhere even though yak tracks weren’t being used.
