    We have a vegan-friendly construction, with breathable mesh and TPU upper materials. There is a full lace-up closure for a secure yet adjustable fit, along with padded tongue and collar.

Updates to Bare Access Arc 4

The upper unit of the Bare Access Arc 4 features a mesh material that has a more open construction than the Bare Access Arc 3. Visible holes pockmark the upper, making sure that air can enter and keep the foot cool and dry throughout every run.

The overlay system was created using a sturdy material. Bonded onto the upper fabric, these sections secure the foot in a snug and customizable wrap.

The outsole unit now has deeper flex grooves in the forefoot area. Having such a construction encourages more freedom of movement. Every toe-off is now more natural and empowered because of the flexibility.

The mesh lining has been treated with an anti-microbial coating that effectively keeps the interior environment of the Bare Access Arc 4 cleaner and healthier for the runner.

This running shoe is vegan-friendly. The materials and components that were used to craft it were not taken from animal products, though they still have 100% efficacy in comfort and service.

Bare Access Arc 4 size and fit

This running shoe was exclusively made for women. It follows the standard sizing scheme for women. It also comes in a medium width, thus accommodating those with medium-sized heels, mid-foot and forefoot sections.


The Bare Access Outsole features gripping lugs that have a 2mm-depth. These aren’t prominent, but they’re effective when exposed to roads and stable off-road tracks.

The Flex Grooves offer natural movement that starts at the edge of the mid-foot to the point where the metatarsals actually bend. These grooves are deeper than the ones found in the previous iteration, so it delivers more efficiency when it comes to its purpose.

The Vibram outsole technology is one of the most durable in the market. It’s made of high quality material that work together to provide a durable outer layer that resists abrasion and wear. It’s also efficient in giving traction.


The MBound is a cushioning technology that has bounce-back capabilities. It’s flexible, but it can carry the foot well. Its soft and responsive nature provides the runner with the capability to function well over many types of terrain.

The Compression Molded Ethylene vinyl acetate or CMEVA offers durability and support in the platform. It doesn’t wear off or break down easily.

The insole was treated with the M-Select Fresh anti-bacterial coating. It protects the foot from moisture and build-up of bacteria. It even adds a bit of cushioning.


The upper unit is made from Air Mesh and synthetic leather. This unit is a durable one that offers breathable and comfortable coverage.

The overlay system is made from TPU, a strong material that’s also responsive. The no-sew construction of the overlays reduces the overall weight and doesn’t make the upper stiff. They help the mesh material wrap the foot comfortably.

The inner lining has been coated by the M-Select Fresh treatment. It doesn’t irritate the skin and it keeps the environment bacteria-free. The neoprene fabric that’s used for this lining is soft and cushiony.
