    The Merrell Bare Access Ultra presents a well-constructed combination of barefoot mechanics and durable, high-performance comfort. The Ultra’s protective features make this one of the most attractive shoes of the fall for natural runners.

    I haven’t had any trouble with blisters from them or anything like that and they actually have a decent amount of cushioning. I haven't noticed any bruising on my feet… I've been pretty happy with them.

    Again though, not a very aggressive trail shoe, so if you want to rip it down a packed snowy mountain, this might not be the shoe for you.

    Although there is much more cushion than with most other minimalistic running shoes, these do offer a good amount of comfortability.

    Supposedly this is a hybrid road/trail shoe, but in my opinion, its a pure road shoe. I expected this one to be simply a replacement of the Bare Access 3.

Updates to Bare Access Ultra

The Bare Access lineup just got better and deeper with the introduction of the Ultra. Considered as the road version of the Bare Access Trail, this low profile shoe is very light, has superb flexibility, and zero heel drop geometry that minimalist runners will clearly love.

The main difference in this shoe and the trail version or most shoes with minimalist characters is the 12mm cushioning offered by the M-Bound midsole. Despite this chunky piece of foam, runners can still get that solid ground feedback and flexibility that are often the trade-offs with this kind of cushioning.

Like its trail cousin, the Bare Access Ultra is versatility personified. It can tackle various distances and at different speeds due to its unique combination of moderate cushioning and light weight. This is another great option for those looking to gradually shift to a more barefoot kind of running or a double-action race day shoe/trainer.

As a superior road shoe with excellent versatility, Merrell also enhanced the durability and traction of the outsole that makes it a nice choice for light trail running.

Bare Access Ultra size and fit

The last used by Merrell normally has a very snug midfoot to complement the decent space in the heel and the wider forefoot. Merrell offers an anatomically-based last that most runners will find very comfortable. There are also enough volume and width in the toe box for a more luxurious feel when racing or training. Medium is the available width of the Bare Access Ultra. Sizing is on the spot with options 6 to 14 for the men’s and 4 to 11 for the women’s.

Outsole

Merrell, yet again, brings the Vibram rubber compound and configuration in one of its shoes. The moderate aggressiveness of the lugs gives the Bare Access Ultra solid grip on practically all kinds of surfaces, except the really rocky, technical, or rugged terrain. Vibram’s new rubber compound promises serious traction, even in wet conditions.

Midsole

The M-Bound DST, which is made of premium EVA and other proprietary materials, is a 12mm cushioning that is quite responsive, very light, and offers decent tactile feedback. It is with this foam that Merrell is able to achieve its purpose of creating the Ultra to be a minimalist shoe with more than adequate cushioning and support.

Upper

The wrap of the upper is very similar to a glove because of its adaptable fit. It has a mesh that is very breathable and bonded synthetic overlays that help lock down the foot. The interior of the shoe is quite plush as it is lined with soft fabric. Considering that the upper is near seamless, runners can run without lesser risks regarding hot spots or irritation. A moderately padded heel and tongue add to the cozy feel. To get a more personalized fit, Merrell uses traditional laces to tie things up.
