Full details

The Vivobarefoot Primus Trail Knit FG Trainers in Purple, size 9, are designed for adult women seeking natural foot mobility and enhanced breathability on trail runs. Their key benefit is a sock-like knit upper made from recycled materials that offers superior trail feel and keeps debris out.

FAQs

How do I know if the Primus Trail Knit FG is right for me?

This shoe is ideal for runners and hikers who prefer a minimalist, barefoot feel, value ground connection, and want good breathability. If you are accustomed to highly cushioned shoes, you may need a transition period.

Can I wear these trainers in wet weather?

The knit upper is breathable, meaning it is not fully waterproof. They can handle light rain or damp conditions, but prolonged exposure to heavy rain may lead to wet feet. They dry relatively quickly due to the material.

What is the difference between Primus Trail Knit FG and other Vivobarefoot models?

The Primus Trail Knit FG is an evolution of the original Primus Trail FG, featuring an updated knit upper for enhanced breathability and a sock-like fit. The 'FG' denotes its suitability for Firm Ground.

Are these shoes suitable for wide feet?

Vivobarefoot shoes are generally designed to accommodate a natural foot shape, which often includes a wider forefoot. The flexible knit upper also allows for some adaptation.

How durable is the knit upper?

The knit upper is designed for breathability and flexibility. While durable for its intended use on trails and paths, it may be more susceptible to abrasion from very sharp rocks or rough surfaces compared to more robust synthetic materials.

What does 'FG' stand for on the sole?

'FG' stands for Firm Ground, indicating that the outsole is designed to provide optimal traction and grip on dry, firm, and mixed natural terrain such as trails, paths, and fields.

Can I replace the insoles?

Yes, the insoles can be removed if you prefer a completely barefoot feel or wish to use your own custom insoles. However, many users find the integrated insole comfortable and supportive for barefoot wear.

Troubleshooting

Shoes feel too tight or constrictive.

Ensure laces are loosened appropriately before putting them on. If new to minimalist shoes, allow your feet time to adapt to the natural fit.

Debris still enters the shoe.

Ensure the sock-like collar is pulled up snugly around the ankle. Consider wearing higher socks if the issue persists.

Reduced grip on very wet or muddy surfaces.

The Firm Ground (FG) sole is optimized for drier, firmer conditions. For very wet or muddy trails, consider alternative footwear designed for those specific conditions.

Knit upper appears discolored after cleaning.

Ensure you are using cool water and mild cleaning agents. Avoid harsh chemicals or excessive scrubbing. Allow to air dry completely.

Setup, Compatibility & Care

Setup: These trainers are designed for immediate use with no break-in period required for the fit, though your feet may need time to adapt to the barefoot feel if you are new to minimalist footwear.

Compatibility: Compatible with most standard socks if preferred, though many users opt to wear them sockless due to the comfortable knit interior. They are suitable for a variety of outdoor activities on firm ground surfaces.

Care:

  1. Remove insoles if applicable and brush off loose dirt.
  2. Use a soft brush and cool water to clean the knit upper and sole. Mild soap can be used sparingly if necessary.
  3. Allow shoes to air dry completely away from direct heat sources. Do not machine wash or tumble dry.
  4. For stubborn stains, a damp cloth can be used for spot cleaning.
