Guidance:
Your measurement is at the higher end of a size but also overlaps with the next size.
In this scenario we recommend the bigger size so they longer, noting they will be a little big to start with.
The measurement is 1-2mm away from the minimum of the next size.
Narrow Feet: Size down.
Normal Feet: Smaller size for better fit, larger size to last longer but may be a trip hazard.
Wide or High Volume Feet: Size up

Honest Prices, Guaranteed.
We are committed to offering you the best value, which is why we price our products honestly 365 days a year.
Because we price our products honestly 365 days a year, we can guarantee you're getting the lowest price available. No gimmicks, no discount tricks. We simply believe that offering customers great products at a great value is the foundation to long-term business success and is the right thing to do.
Responsive Production
All BGreater are handcrafted in small batches. By producing in small lots we are able to minimize waste and overhang and churn inventory more quickly. As a result, we don’t have to build the cost of "excess inventory" into our prices, allowing us to pass along those savings to you.
Lean Business Model
BGreater was originally "bootstrapped" with our limited personal savings, which taught us how to be smart with our money. We keep fixed costs low and do almost everything in-house with a hard working team who believes in the mission, opting for equity ownership over high salaries.
Long-Term Thinking
While most "business people" tell us our markup is too low, we disagree. We are forgoing short-term profits in exchange for offering our friends, family, and customers a better value. This is something we are very proud of and believe will pay off in the long-term; after all, great products at a great value never go out of style!
Our Story
The best choice for your children's feet
We believe that barefoot shoes are better for everyone – that’s why we want to get kids off on the right foot and start their barefoot journey as soon as possible.
Founded by parents, for parents
I’m Iain, founder of BGreater, and like most parents, I want the best for my two children. After my own rehab and wellness journey educated me on foot health and barefoot shoes, I took what I’d learnt and used it to support my children’s health.
So Comfy, They’ll Forget They’re Wearing Them
No Squished Toes
Our shoes are designed with a wider toe box that mimics the natural shape of the foot for healthier foot development.
Long Lasting Design
Soft, durable leather, a hard wearing sole, and toughened toe bumpers, our shoes are built to outlast your kids' growing feet.
Sensory Superpowers
With a thin, flexible sole, our barefoot shoes let kids feel the earth, activating their senses and connecting them to their environment.
Posture Perfect
Proper foot alignment starts with the right shoes. Barefoot shoes encourage a natural gait, helping to develop strong muscles and good posture from the ground up.
Extra Growth Room
Parents report their kids outgrow our shoes because of the extra growth room and durability.
Ultra Stylish
Designed from the ground up by leading UK shoe experts, we don't compromise style for comfort.
Why Traditional Shoes Might Limit Your Child's Happy Feet
Traditional shoes with their narrow design can restrict your child's foot growth, impacting their natural movement and connection to the world. By choosing barefoot shoes, you empower their little feet to move freely, ensuring healthy development and joyful exploration. Let them experience comfort and natural growth, just as nature intended.

How We Compare
Why We Exist
After being medically discharged from the British army, I learnt how much shoes affect kids' foot development. Witnessing my son's feet change in regular shoes inspired me to create a solution.
BGreater was born: premium, affordable, foot-shaped shoes, crafted by experts for lasting comfort and durability.
