Rated 5 out of 5 by from Happy Feet While working at the Adventure Store in Yellowstone National Park last summer I mentioned to my boss that I was in the market for a new pair of hikers. Without hesitating she led me to the Merrell shoe display and pointed out the Grassbow Airs. After a very brief walk about I purchased the Grassbows. They are simply the very best hiker/trail running shoes I have ever worn and that is saying a lot. I have worn them on all types of terrain. They are light, offer great support, and let my feet breath. Five Star comfort. I have put away my Asics and New Balance and now ignore my Brooks. The Merrell Grassbow are and will be my shoe of choice. Ordering second pair now....

Rated 5 out of 5 by from Great for long distance hiking I wore these shoes on a three month section hike of the Pacific Crest Trail. Hands down, they are the best hiking shoe I've ever purchased. They performed awesomely in varied conditions, including the SoCal desert and the southern High Sierra Mountains. They can even be fitted with traction devices for the snow. Grassbows breath like trail-runners but offer enough protection to be considered a long distance hiking shoe. My only complaint is that you have to replace them about every 800-900 miles, but that's pretty common. Highest recommendation.

Rated 5 out of 5 by from Great for the concrete jungle I purchased this shoe for a lot of walking on hard pavement during a vacation to the east cost of the USA. Although I'm sure this shoe will be fine in the mountains, I want to use this shoe for practical day to day activities. After hiking up many flights of stairs, walking across bridges, or walking on uneven pavement to and from events, my feet felt just fine at the end of a long day. The fabric allowed air flow and kept my feet from too much heat and sweat. Its very light but kept up to the Merrell hiking standards. I have/had 3 other Merrell hiking boots which I used for similar purposes.

Rated 5 out of 5 by from Very comfortable I'm a trail runner and like light shoes. These feel like I could run in them, very light and well made. On my first day with them I went 8 miles in Yosemite. Normally, after a long hike I can barely wait to take off my shoes and put on flip-flops. I didn't feel the need to take these off. I also expected hot spots or blisters for wearing new shoes for the first time. None. I couldn't get over it. Last weekend I took them through the snow in Tuolumne and then through desert scrub near Mono Lake. These are the best hiking shoes I've owned in 30 years of hiking.

Rated 4 out of 5 by from Surprisingly Good Lightweight , comfortable and highly breathable. I bought this shoe for light hiking and around town use. The majority of use is on 3 - 4 mile hikes on mixed terrain. I have found the Grassbow to be surprisingly durable although I wouldn't take them off a groomed trail. I might have given five stars except for the useless insole that comes with the shoe. It provides no support or cushioning. Do yourself a favor and pick out a better insole if you plan on any kind of serious walking or light hiking. Otherwise, I highly recommend this shoe for summer use.

Rated 3 out of 5 by from Not for everyone I've had plantar fasciitis on and off and for some reason these shoes seem to really aggravate my "bad" foot. I tried them twice for around 10 miles and both times my foot was screaming. On the other hand I also picked up a pair of Solomon's and had zero problems. As a matter of fact I wore the Solomon's for a 5 day 50+ miles backpacking trip brand new out of the box after I realized these shoes were not working for me. Then I gave the Merrel's another try thinking maybe it was just my foot at the time, but same results. I also do not like the laces since they seem to too slick and like to loosen up too easily. The laces on my Solomon's do not have this problem.

Rated 5 out of 5 by from I don't even notice their on my feet! I bought these about a year and a half ago. Great shoes! Didn't use them much for hiking as intended. Mainly worn at work and urban trekking. Only about a month ago i forgot my running shoes at gym and ran in these. Next day i threw my running shoes away! These Merrells are extremely light and breathable without sacrificing support! I will buy a second pair when its time.

Rated 4 out of 5 by from Good lightweight and comfortable hiking shoe. I purchased these shoes several months ago to use for day hiking. Have done about 10 trips from 5-10 miles in them. They provide adequate support and fairly good traction. Fit is true and very comfortable. Once in a while I have slight slips on smooth steep descents. Some areas with lots of sharp rocks can get tiring as expected with a shoe this light. Might try the superfeet from my ski boots to see what that does.

I would like to buy these for my son but he fits best in wider shoes. Does this shoe run wide or narrow?

Asked by: Los Altos
The Grassbow Air Low Hiking Shoes are a standard width; they do not run wide or narrow but are true to size.

Are these good for backpacking or mainly just regular hiking?

Asked by: JKHiker
These can be used for backpacking and are a good choice if you want to save weight, but they are not as supportive as backpacking boots would be. If you do not feel like you need the support of a backpacking boot, these shoes are a good choice.

I wear Jungle Mocs in size 8.5 and wonder if these hiking shoes fit about the same or stretch with time.

Asked by: MadisonGrog
You should be okay with an 8.5 in the Grassbows as well. The feedback from Merrell is that they are sized as expected.

In street shoes I wear a size 9 but my Oboz hiking boots are a 9.5...what size would you recommend in this shoe for hiking/backpacking? I really like my Oboz but I'm looking for a lighter alternative for an AT thru hike.

Asked by: Ole Whiskers
​We recommend sizing similar to your Oboz for this hiking shoe.
