Though our shoes are not 100% barefoot minimalist shoes, they are very much inspired by them. The sole thickness falls between 7 and 14 mm, depending on which shoe and cushion you get, and the sole's flexibility responds accordingly. Our BioStride has a small 2 mm drop, but all of our other shoes are made with zero drop. The average shoe weighs 200-350 grams (depending on foot size) and doesn't utilize unnecessary add-ons. Overall, these are shoes that can introduce the fundamental benefits of minimalist footwear, and the BioStride is an excellent place to start. For people already experienced with barefoot shoes, explore our BioRunner with the minimal (flex) sole option.
