Rated 5 out of 5 by from Asolo is Great!! THESE ASOLO BOOTS WERE THE ANSWER TO MY PRAYERS! I can hike again finally! I have a foot injury I will have to consider every time I buy a pair of shoes from now on. I have plantar fasciitis and I needed a stiff sole. I didn't realize the break in time these would require and my body had to get used to them too. I do have fairly flat feet and these boots do not have a very high arch which is great. I feel supported by them when I lift heavy loads and I am comfortable during and after the hike. I do not use them for everyday use as I find them uncomfortable on pavement (but then again I don't believe they were made for pavement). I just love these boots!!

Rated 5 out of 5 by from 1000 miles later, heck yes, nice boot! :) I bought these first part of June 2016, they fit my slightly wide front foot/narrow heel combo super well. Toe box is super strong, mine has taken a lot of rock hits. I do all kinds of climbing and hiking in these boots on Hood, the Gorge, the Coast Range, Central Oregon. Break-in on my heels was rough because I didn't keep the laces snugged well toward the end of a 24 mile loop around Three Fingered Jack. Stiff and protective soles, great dry and wet rock traction. Waterproof, too. I did buy other insoles for mine, which is pretty much all my boots (ski, tele, etc) get better insoles. I've hiked scree to mud and everything in between with these and I love them. Really great boots!

Rated 5 out of 5 by from Love this boot I bought this boot last summer to do the John Muir Trial hike in the fall. I broke them in prior to going - about 3 miles a day for a bunch of days of walking on country roads- never a blister(I used a single sock layer when I broke them in and double socks-one thick and one thin- both wool) for the hike- only blisters I had were late in the hike and they were minor. These were one of my most favorite items on the trail- I really liked the way they feel on my feet- lighter than most of the all leather boots, but with great support. They held up very well, kept my feet relatively cool when it was hot and comfortable and dry when it snowed - 12" over Mt Whitney - all in all a really good boot.

Rated 5 out of 5 by from THE boot I've been wanting a good backpacking/hiking boot that will last a while and be comfortable for a long time. I went into my REI and tried on several boots, but ended up trying this one on a few times. I wanted there to be something wrong with them. It was just too good to be true. It had to be. But, after reading so many awesome reviews, I decided to give them a go. This boot is incredible. Broke in great, saved my ankles a couple times, and not a single sore or blister after 28 miles in the wet, slippery, rocky Smoky Mountains. They dried quickly when they got wet (never wet on the inside) and I never had a point where I was ready to tear off my boots at the end of a long day. I'm so happy I found my boot.

Rated 3 out of 5 by from Asolo Fission I wish I could've kept this boot because it is perfect for my plantar fasciitis and it is sturdy. I experienced strain at my achilles while hiking. And after the hike I would have pain at the ligaments at my ankle that I sprained 8 years ago and stiffness/pain at my ankles the next morning. I think it's a great boot, but unfortunately not for me. I've never owned a boot like this before so maybe I don't understand what it takes to break it in. But I wasn't willing to risk injuring myself to find out. I hike average 5 miles a few times a week. I just got back into hiking after 3 years of healing from plantar fasciitis. I do think it's a great boot, just not for me. So today I returned them and I'm trying another pair of Asolos.

Rated 2 out of 5 by from Seam Gave Me Blisters I wore these for a short 3 mile walk and no matter how I tied them, I was getting rubbed on my heel from the seam. However, I did spray them with the hose and I can tell you they are waterproof! I am a size 7 and wore a size 6.5. The shoe does run wide (which is great for people with wide feet like me). It's a shame that seam rubbed because other than that they were very comfortable. However, I purchased them at a garage sale on a buy one get one free deal with a pair of Lowa Renegades (which I highly recommend if these boots didn't work for you!), so I'm not heartbroken and am thoroughly happy with the other half of my purchase :)

Rated 5 out of 5 by from AMAZING BOOTS!!! Purchased these for a 120 mile hike from Denver to Breckenridge, hiked about 5 miles total to break them in a week before the trip. We averaged 15-20 miles a day, easy to rough, dusty to mucky muddy terrain and they were AMAZING! I wore thin socks (the double layer blister socks) also-- even in 90 degree heat my feet did NOT sweat. After the 120 miles they still look and fit like new.. just had to hose them off! I normally wear an 8 but had to go with an 8.5. I highly recommend!!

Rated 5 out of 5 by from Much less foot fatigue I love these boots!! I had the old leather version and bought these hoping they would be a bit lighter and more comfortable. I loved them so much I did a 10 mile hike when breaking them in and I could have gone even longer! You barely feel the rocks and feel very secure. I had no rubs or sore spots. Most importantly, when I finished- I didn't feel like ripping them off and getting Into more comfortable shoes. I cannot say enough good things about these boots.

Questions & Answers

Do these run big, small, or true to size? 

Asked by: trefrogz
They run big!!! I had to return my 7 for a 6.5. I would definitely try them on. Some people said they needed to go one full size down.

What features make this boot exclusive to REI? How does it compare to the other 2016 Asolo women's boots e.g. the Futura GTX? And the much beloved and discontinued Asolo Attiva GTX? I am looking to replace the Attiva GTX after 6 years of heavy use.

Asked by: Beeeater
Asolo made the Fission GV Hiking Boots just for REI. They are very comparable to the older Attiva GTX Hiking Boots. Both have a thermoplastic urethane shank, Gore-Tex waterproof/breathable membrane and suede leather upper. The Fission GVs have a slightly better outsole with Vibram rubber.

I have been wearing the Men's Asolo Drifter's for a while. I love everything about them except the weight. These appear to be nearly a pound lighter? Other than weight, what are the differences? Support? Or just ave men's size is more than ave women's?

Asked by: Lady Bigfoot
The Fission is very similar to the Drifter and have most of the same features. They are lighter because they are a women's boot and are much smaller than the men's, but sizing aside they are very similar in weight. The main difference will be that the men's Drifter is wider because it is a men's shoe and the Fission will have a much more narrow fit.

I also have the problem several others have mentioned of these boots blistering my heels repeatedly on hikes with elevation gain. Does this eventually go away? Any suggestions aside of tightening the laces?

Asked by: sbh246
Besides adjusting your lacing technique, you may try replacing the insoles or making sure you have on appropriate socks. Here are some tips on boot fit:

Asked by: njuneja
Both boots are very sturdy and are excellent for backpacking, but the Fission is much lighter weight than the Stynger.
