    Crafted from vegan materials, the BioWorld Petra barefoot sandals maintain ethical values without compromising on quality. The microfibre upper and lining offer a light and soft touch, ensuring all-day comfort. 

    The Vibram lightweight and flexible outsole offers superb groundfeel, while the buckle-fastening ankle strap keeps the foot securely in  place. 
    With the stylish design and elegant cut of the upper, these closed-toe sandals beautifully complement summer dresses or tailored pants.

    While the toebox is optimally shaped  and  provides  room  even  for a dominant big toe, these sandals are best suited for narrow feet or those with lower volume in the forefoot area.

    Ethically crafted in Europe by a family-run company with over 100 years of shoemaking experience, each pair is created with attention to detail and a commitment to quality. Embrace sustainable fashion and step into elegance with the BioWorld Petra barefoot sandals.


    Bubbly Toes MeasurementWe recommend that you always measure your feet prior to every purchase - don’t just order your usual size. Check the Sizing section for internal length / width dimensions and the Sizing help page for more information.

    When selecting your size for sandals, it's important to consider that you may not need as much extra space as you do with closed footwear. In general, 5-8mm is plenty to ensure a good fit.  

    Bubbly Toes Barefoot Size Chart Information

    We recommend that you always measure your feet prior to every purchase - don’t just order your usual size.

    The length and width of each sandal is carefully measured so you can easily select the most suitable size. Length is measured through the longest part of the sandal (usually heel to big toe), and width is measured across the widest part of the sandal, edge to edge.
    Length wise, your feet will require slightly less extra space in any open-toed sandals as opposed to closed-toe shoes. In  general, 5-8mm is plenty to ensure a good fit.
