Rated 3 out of 5 by from Super comfy shoe with durability issues I purchased these one month ago and have run 75 trail miles in these shoes. they are a dream to run in. Very comfortable on all terrain the Pacific Northwest has to offer, great for short or long runs..However I am finding that the toe guard is beginning to peel off as are the heel lugs on both shoes as well as some wear and tear on the mesh upper,. This seems like excessive wear for only 75 miles of running, mostly on dirt trails. For the price of the shoe I hoped for more durability.

Rated 2 out of 5 by from EASY TRAILS ONLY I bought these 2 weeks ago, hoping for a more durable replacement to the Altra Lone Peak 3.0 shoes I had. I plan on hiking the PCT this summer, so I need durability, traction, and comfort. Within a week (about 20 miles), a crease formed where the rubber rand meets the mesh at the flex point of my foot. The mesh started tearing as well, so I knew they would not hold up. Also, the tread has very small lugs. They do not have good traction in mud, so these would be best for trails like dirt roads, without much elevation gain. They were comfortable at least!

Rated 4 out of 5 by from Very cushioned shoe I originally purchaser a pair of Brooks GTS 17 running shoes but my toes were too crowded in them so I exchanged them for these and I'll have to say that I have never worn a shoe with as much cushion as these. I purchased them as a walking shoe and general use.I have noticed while walking on asphalt that the treads on the sole are kind of loud as they are gripping the surface so I'm interested in seeing if they wear out fast because of this.I really like the looks feel and comfort of them and the whole experience with REI was great as well.

Rated 5 out of 5 by from Excellent Trail Shoe This is my second pair of Brooks trail running shoes --- my first pair was the Pure Grit 3 and they held up extraordinarily well, having been through multiple Spartan races and Tough Mudders, plus the 150+ miles training in them over 18 months of use. They finally needed replacing so I purchased the Caldera, a nice step up (pun intended, hahahahaha) and I am loving this shoe. The Caldera has slightly more arch support and an excellent tread grip pattern. I've tested the Calderas on 10 miles of extremely swampy, rocky, rooty and hilly terrain and no slippage issues at all. They shed water quickly and dry very well afterward. I also like the extra eyelet that helps tie the shoe more securely around the ankle -- people at obstacle course races occasionally lose shoes in deep mud but the Calderas will not come be lost given the extra eyelet. This shoe looks beefy and heavy but it is not at all; it's quite light and has a bit of extra spring in the step but still offers a very stable feel. One bit of advice --- get these in the High Risk Red color --- MAJOR head turner. I've had many people ask me about these shoes because that color rocks, especially on the trail :)

Rated 3 out of 5 by from Comfy but limited to easy trails only I bought this a couple of weeks ago and so far did a few short runs along smooth trails near my house and a technical half marathon over a rocky terrain. The shoe is very comfortable and is excellent for smooth terrain. Unfortunately it lacks any sort of protection from rocks nor support is any good on the uneven terrain. The only thing I gained over running in my regular running shoes is traction, otherwise I am not sure why it's considered a trail shoe.

Rated 3 out of 5 by from felt great, sole shredded quick. i bought this shoe looking for more cushion than the Pure grit which i loved,but feet to a pounding racing on slick rock in Moab, theses Caldera where great and comfortable but after only 120 miles the cushion around the lugs where shredding. $1 a mile seemed like a lot for the shoe so i returned them. sad because my feet liked them. though the lugs weren't huge i always had plenty of traction......while they lasted. torn betweeen buying them just fro races or continue my search for another shoe

Rated 5 out of 5 by from Grippy trail running shoe I have put almost 400 miles on tough trails running in these in the last 3 months. I think they are great for mixed traction. They have a stiffer sole to reduce pointy/ jagged rocks from protruding. There is good support. There is not a lot of drop in this shoe, so you may find them a little awkward on the pavement, but again this is a trail shoe. These are not great mud-shedding shoes and the upper is kind of thin which makes your foot get wet pretty fast with even asmall splash. I personally think they do everything and more for hard-pack, rock-scrambling, and fire-road.

Rated 3 out of 5 by from 1/2 size big, wide, squishy I’ve been trail running in this shoe for about a month now and they are definitely a half size too big (I recommend ordering half size smaller than normal). They give me hot spots on longer runs and the tread isn’t aggressive enough on loose trails going up or down. The front third of the shoe is bulky and a little wide for me. If you have thick bulky feet and toes you will like the space if not the material folds and bends too much making them uncomfortable. The cushion is too soft, although on cold days it’s not bad as the cushion firms up. I like the 4mm drop and thought for winter running the extra cushion would be good but all and all this just isn’t the shoe for me. I’ll go back to the saucony peregrine which is my go too.

Are these intended to be winter/cold weather shoes? I have these and love them, BUT my feet sweat just sitting still. I'm wearing super thin high quality/breathable biking socks and my feet still sweat just wearing these shoes around the house.

Asked by: JoeyV
These shoes are not insulated and they are not designed to be a cold-weather shoe.
