Insole & Sizing and How to Fit Yenta + Posha Shoes

Yenta + Posha shoes are specially designed with podiatrist-approved, patent-pending, removable orthotic insoles. These insoles were created for our shoes, but their thin profile make it an easier fit for your other footwear. We are excited to be one of the first companies using bamboo charcoal leather as a cover. This material absorbs sweat and toxins, and is treated with an aegis microbial, a highly-effective antibacterial shield. The cushioning is Poron which allows for ultimate shock absorption without any breakdown over time. For added support, we extended the semi-rigid shell, so it hugs the side of the foot and added solid gel under the heel. Surrounding this gel, we hid a strip of EVA between the layers which is material often used in tennis shoes.

The insole that is available for purchase is a rounded-point shape and will fit majority of shoes, regardless of toe shape. Please note the insole is thinner than most on the market but will add 2 – 2.5mm to your shoe. If your shoe just fits or is tight it will not fit correctly. 

The research behind the insole is extensive and based on biomechanics. Without getting too far down the rabbit hole of science (we’ve learned that not everyone likes talking about feet as much as we do!), here’s a quick explanation of how the insole offers its outstanding support and comfort.

When you take steps, your foot is supposed to behave in a specific, predictable way. The foot needs to have a certain amount of pronation (the rolling inward of the foot) and supination (the rolling outward of the foot). Most people, however, don’t follow this gait pattern — and poorly-designed shoes are the biggest culprit behind ineffective and painful gait patterns. 

Our Fluid Gait Technology allows for and encourages the proper amounts of pronation and supination. We teamed up with an expert Orthotist and Podiatrist to infuse our shoes with this Technology, which was created to enhance the foot’s natural walking motion.

The semi-rigid shell of the insole allows for perfect balance throughout the gait cycle. The ground-reaction forces for the entire foot are more evenly distributed, so the pressure pattern results in a more balanced gait picture. Not only will this help your gait motion, but it will also improve your overall posture and movement efficiency.

Proper shoe fit considers multiple factors. All of our shoes are built to fit the true form of the foot in Women’s width B or Medium which is considered the average width and can run a half size large. There is some wiggle room as our materials used are very flexible and comfortable.
