Have you ever noticed how high-quality things work better, last longer, feel right? That’s why we’ve always been drawn to the finest SOLE materials the world can provide. Vibram® is world famous for being wizards in the field of soles and working with them, we’ve perfected OURS. ### GEN3WINGS The most secure yet minimal foot harnessing system yet - optimal performance and ease of use - minimal hassle = maximum up time.

Innovations in material combinations have lead to old time favorites.
Sizing and fit
Barefoot sizing varies by brand. Use the brand size chart for the final call.
Most men tend to size down 1/2 to a full size with LUNAs. Most women are true to size. With LUNAs, you want a close fit and not a lot of space around your foot. For more detailed guidance and support, please visit our size guide.
Golden Toe note
Why it earned a Golden Toe note
Slightly more durable sole. I DO live in Hawaii where all pavement and rock surfaces are WAY more abrasive than the mainland due to the volcanic nature of things so that likely plays a big role but the fit is incredible once adjusted. Also run in the rain A LOT in these. No dealing with soggy shoes afterwards.
