Meet Bolt — built for feet on the move.

Barefoot-friendly and Podiatrist-approved, Bolt is made from durable, responsibly-sourced leather that moves with growing feet, not against them. The wide toe box gives little toes room to spread and grip, while a genuinely flexible sole keeps every step natural. Unisex, effortlessly cool, and tough enough to keep up — Bolt is for kids who don't slow down.

Child-friendly design makes Jett easy to get on and off (and easy to get just right), while the lightweight, cushioned feel keeps little explorers comfortable all day. Thoughtfully made and consciously designed, the adjustable fit allows them to grow as they do and  last longer. Jett supports natural movement, independence, and durability — without compromising on style.

Planet-conscious, podiatrist-approved, and designed for real life with real kids.
Because first shoes should feel like barely there shoes.

3. Simple Measure Method

If you don't have a printer, follow the simple steps below. You will need: a pen, paper and ruler.



We're here to help, so email us at help@zigandstar.com if you have any questions. 

We hope you love ZIG+STAR shoes and get as much wear out of them as you possibly can. We think a few scuffs add to the story of their adventures, but a little bit of care will help them last longer.

  • Leather is a natural, breathable material - if it becomes wet, pat with a dry cloth, and leave to dry naturally, out of direct sunlight (keep away from radiators!)
  • Mud is best removed by leaving to dry out and remove with light brushing. Any remaining marks can be removed with a clean, damp cloth.
  • Keep fastenings fresh by brushing away any fluff with a clean toothbrush.
  • Light scuffs can be sorted by rubbing a matching coloured shoe polish over affected area.
  • Do not bleach, soak, machine wash or tumble dry.

  • OUR ETHOS

    ZIG+STAR is a modern kids’ footwear brand built on the belief that great design and sustainability should go hand in hand. We make shoes that are cool, unisex, and built to last — not just for one season or one child. Every pair combines comfort, style, and planet-friendly innovation, with clever features like removable midsoles that grow with little feet and materials chosen to reduce waste and carbon impact. We’re on a mission to give growing feet a smaller footprint — proving that kids’ shoes can look amazing, feel incredible, and do good for the world they walk in.

  • OUR MATERIALS

    At ZIG+STAR, we carefully choose materials that are kinder to kids’ feet and the planet. Every component is selected for comfort, durability, and lower impact, and we prioritise suppliers who share our sustainability values, ensuring traceable and responsibly sourced material. We use Gold-certified LWG leather which comes from tanneries that meet the highest environmental and ethical standards and is produced using responsible water, energy, and chemical management, with traceability - Gold certified is the highest standard within global leather production. We use Natural Rubber in our outsoles, known for its durability and anti-slip qualities. Our packaging is FSC certified, recyclable (and reusable!) and we continually explore new innovations that reduce waste and emissions. By combining premium craftsmanship with conscious design, our shoes prove that sustainability doesn’t have to compromise on style or performance — because what goes into our shoes matters just as much as what they stand for.

  • OUR IMPACT

    ZIG+STAR is committed to reducing its environmental impact at every step.... This starts with our sustainable "Good-To-Grow" design, follows through to production and our circular solutions -  Our Trade-In scheme means your old shoes can have another life through our donation charity partner, Sals Shoes, or we recycle them free of charge to divert them from landfill.  Through validated climate mapping with Climate-KIC, we've estimated that every pair of ZIG+STARs saves approximately 1.6 kg of CO₂e compared to conventional footwear. For the average family, that's a saving equivalent to the carbon absorbed by a mature tree in a full year. There is so much more we want to do but by focusing on extending the life of our products, sourcing responsible materials and offering end-of-life options, we are showing that even small steps can add up to a lighter footprint for the planet.

FAQS

A: A barefoot shoe is designed to let a child's foot move as close to naturally as possible while still offering protection from the ground. For a first walker, this is particularly important because the muscles, tendons and bones in the foot are still forming. A shoe that is stiff, heavily cushioned or too narrow can interfere with that development. The Jett's thin, flexible sole allows the foot to feel and respond to the ground beneath it, while the wide toe box gives little toes the room they need to spread and grip naturally with every step. Podiatrist approved, it is built around what developing feet actually need, not just what looks supportive.

A: Absolutely. The Natural Animal print sits on genuine premium leather uppers, crafted from Gold-certified LWG leather, the highest standard in ethical and environmentally responsible leather production. The print is part of the leather finish, not applied on top, which means it does not crack, peel or fade with normal wear in the way that surface treatments can. You are getting the same premium build quality as every other ZIG+STAR shoe, with a colourway that tends to be a firm favourite for parents who want something a bit more distinctive than a plain neutral.

A: The Jett features ZIG+STAR's innovative removable midsole, which is the core of the Good-To-Grow concept. When the midsole is in place, it optimises the fit for the current size of your child's foot. As their foot grows and the shoe begins to feel snugger, removing the midsole effectively increases the fit by half a size, giving the shoe a longer useful life. This is particularly valuable in the first walker stage, where feet can grow quickly and a single pair of shoes can otherwise be outgrown in weeks. The midsole also adjusts the fit for narrow or wider feet, making the Jett one of the most adaptable first walker shoes on the market. Browse the full first walker range at zigandstar.com/collections/first-walkers.

A: Yes, and it is a straightforward process. ZIG+STAR offers a 21-day no-questions-asked return policy on unused shoes in their original packaging. Email help@zigandstar.com with your order number and the team will arrange a free return or exchange. Before ordering, the most reliable way to get the right fit is to use the ZIG+STAR mobile foot measuring tool, which walks you through a precise foot scan using just a sheet of A4 paper and your smartphone. The size chart already accounts for room to grow, so order your child's true measured size.
