Rated 2 out of 5 by from Bring the old Bare Access back! I was looking for a minimalist, comfortable, breathable, zero-drop (or as close to it as possible) shoe and bought this a couple of years ago. They were the most comfortable shoes I had worn in my life! I could feel the ground. I could let my own feet take care of balancing. It fit well. Snug, but enough room for my toes. I could wear them all day. After heavy mileage and wearing through the sole, I wanted to replace it with the same model. Alas! The new Bare Access 4s have what I consider too pronounced an arch support. That disqualifies it for me. I am going through the seven stages of grief while looking for an alternative.

Rated 5 out of 5 by from Initial Observations Just purchased these at my local REI store in Charlotte and have walked a couple of miles in them. Very light and comfortable as expected. My running shoes are all size 14 and street shoes are 13s. I thought since this was a minimalist shoe that I would need a size 13 but it was a little tight...the 14 was a hair big but it worked for me. This is the first minimalist shoe that I've ever had so I will break them in as the salesperson recommended by starting out at only 10% of total mileage with them. I've never had any type of running issues (been running for 30 years) so I'm trying to add a little bit of 'spice' to my running with these type of shoes. I will use them as my go to shoe since they are so light and comfortable. Also, if you go to the store in Pineville, ask for Al as he is the extremely knowledgeable about these type of shoes.

Rated 2 out of 5 by from Poor construction I purchased these during a sale to replace an older pair of Merrell Men's Trail Glove 2 shoes that I have been using at the gym and for some light hiking. On my second time wearing these shoes at the gym, I noticed an odd sensation through the sole of my foot and saw that 1+ inches of tread on the shoe had torn and begun to lift off. Maybe I got a bad pair with poor cementing of the tread, but it also seems like a design flaw to have so many separate strips of tread on the sole. To me, more strips of tread = more seams = more potential points of failure. Until the tread failure, they seemed comfortable and both the uppers and welt appear well-constructed like the other Merrell shoes I have owned. I love the Merrell Trail Glove series and will transition back to them. These shoes will unfortunately be returned to REI.

Rated 5 out of 5 by from These shoes have changed my life What can I say - these are wonderful shoes! As others have mentioned, they're not really trail shoes, and they're not really minimalist shoes, but they are super light, have pretty decent arch support, and are zero drop. Suitable for running on the road/mixed terrain - great traction. They have the padding necessary to pound the pavement for miles on end. The arch support is what does it for me. I've been battling plantar fasciitis issues for the better part of 10 years. I used to be limited to heavy shoes with bulky inserts to log the mileage, but this shoe has changed all of that. The drop allows for natural stretching of the calf muscle as I run, and the arch support takes a lot of stress off the underside of my foot. The result: miles of pain free, light weight running! I'd definitely recommend this shoe to anyone looking for a little P.F. relief. The only downside (if you can call it that), is that wearing these shoes makes me about an inch shorter compared to my old ones. Time to buy new jeans, I guess...

Rated 2 out of 5 by from Very Strong Arch Support I just bought these and am returning them immediately. The arch support is the strongest I've ever found in a sneaker, such that the mid-sole feels pinched/squeezed. If that is something you're looking for, these might work for you, but the product description should make clearer how strong the arch support is.

Rated 5 out of 5 by from My feet love these shoes! I love these shoes. I've been using the early model Altra Instinct until I've worn them out; they accomodate my forefoot like toe shoes do. Now I've tried the Merrell Bare Access 4 Trail and I love them. Most of all for: room for the full forefoot and room for the toes to splay. Also for lightness and simple design. Thinking I better stock up on a few pairs as a hedge against being bereft of shoes that are very friendly to my feet (the acid test). (I tried on in-store, but exact size only available online.)

Rated 4 out of 5 by from Not what I expected These shoes look like they are designed and built well but I was unable to fit into them. The merrel water proof boots and the low top hiking shoes I bought supported a wide foot. These running shoes are very narrow and probably fit for an arched foot. I was disappointed in the inconsistency of the fit among different merrell model shoes. Always a good idea to try them on in an REI store and have a knowledgeable member direct you towards the proper shoe.. that's how I purchased my first pair last summer.

Rated 3 out of 5 by from what is it? I run on trail with NB Minimus on trail and love my Kinvaras for longer runs and the actual marathons/half-marathons I race, but they are wearing out quickly, so I was looking for a minimal road shoe for all my training road runs <12 miles (over 12 and I need a bit more cushioning under my feet.) My initial intent was to get the road Minimus, but when I saw the red version of these at a drastically reduced price on the REI outlet store, I jumped on it. These aren't that light for a minimalist road shoe because they have toothier tread than most road shoes. REI markets them as road shoes, amazon sells them as trail shoes and the Merrell website doesn't really say what the intended use is. A lot of my runs have a mix of trail and road, so I guess I know what shoe to grab for those runs. To call these minimalist shoes is a bit of a stretch. Sure, zero-drop and the not-so-padded heel is enough to encourage mid/forefoot striking, but beyond that, there is not much road feel in the toes due the the thick rubber and the mid-foot is stiff and supportive with high arches, which many may like, but if you're looking for a barefoot feel this isn't your shoe. The high point in that regard in comparison to the Minimus is that there is more room in the toe-box to "splay" your toes out like you might if you were barefoot. In summation, these are kind of an in-between shoes; Somewhere between a road and a trail shoe, not quite a normal running shoe, but not quite a minimalist shoe. That may be exactly what some people are looking for but I wanted a minimal road shoe so for me they are in-between good and bad and I have rated them accordingly.

I am thinking of buying these. Does my size 9 in Merrell Trail Gloves that I own currently correlate with my size in these? Because they aren't quite as minimal, I am wondering if a size 9.5 is more appropriate?

Asked by: Tulenkot
If you wear a size 9 in the Trail Gloves, we recommend the same size for these shoes.

I've had ITBS problems running and I am reading Born to Run which makes the case for more barefoot minimal running shoes. Does anyone's have experience with knee pains (like all runners) and have these shoes helped?
