The short answer: The safest kids’ shoes are the ones where the brand can tell you exactly what every part is made of: upper, lining, insole, sole and glue. Avoid PVC and vinyl, be sceptical of “waterproof” (it often means PFAS) and of vague labels like “man-made materials,” and know that US law caps lead in children’s shoes but does not restrict phthalates in them.
When I became a parent, I started reading labels on everything: snacks, sunscreen, laundry soap. Then I picked up a pair of kids’ shoes and realised the tag said almost nothing. “Synthetic materials.” That was the whole story.
So I went looking for answers. This guide is what I wish had existed: a plain-English checklist for choosing kids’ shoes you can actually feel good about, whether or not you ever buy ours.
Why shoes deserve the same scrutiny as everything else
Children spend hours a day in their shoes: warm, enclosed, sometimes against bare skin, then kicked off in the car and picked up with their hands. We check the ingredients in what goes into small bodies. Shoes rarely get the same attention.
There is also a gap that most parents don’t know about. In the US, the CPSIA applies to children’s footwear and caps lead in children’s products, but footwear is specifically excluded from the CPSIA’s phthalate restrictions, which cover children’s toys and childcare articles. Some state laws and retailer standards go further, so compliance varies from brand to brand. The takeaway is simple: “It’s a children’s product” doesn’t tell you what’s in it.
Independent testing shows why it’s worth asking. Tests commissioned by the Czech nonprofit Arnika found the phthalates DEHP and DiBP in children’s summer shoes, and lead in several samples. Only one pair in the sample had neither. That is one European study of one product category, not a verdict on every shoe, but it shows how much can hide behind an innocent-looking pair.
The 6 things to check before you buy
1. Can the brand name the materials?
Look for specifics: vegetable-tanned leather, natural rubber, organic cotton, cork, plant-based foams. “Synthetic,” “man-made” or “performance materials” with nothing more is a signal to ask. Transparency is the single best predictor of a brand that has thought about this. If they know what’s in the shoe, they’ll say so.
2. Is there PVC or vinyl?
PVC (polyvinyl chloride) is a plastic that often relies on plasticisers such as phthalates to stay flexible. Consumer groups consistently advise parents to avoid PVC products. Check soles, straps, decorations and add-on charms, which are often PVC even when the shoe itself isn’t.
3. What about phthalates and lead?
Lead is regulated in children’s products, including shoes, in the US. Phthalates in footwear are not covered by the federal phthalate rule, so a brand has to choose to test for them. Ask directly: “Do you test for phthalates, and can I see the report?” A confident brand will answer. A vague one tells you something too.
4. Is it “waterproof”? Ask about PFAS.
PFAS (“forever chemicals”) are widely used to make fabrics water- and stain-resistant, which is why waterproof shoes and boots deserve extra questions. Be careful with green language: Silent Spring Institute researchers found PFAS indicators in waterproof children’s products marketed as “nontoxic” or “eco-friendly,” including some carrying Oeko-Tex or Greenguard Gold certification. The practical rule: for any waterproof or stain-resistant shoe, ask for a specific “PFAS-free” statement, ideally backed by testing.
5. What about glues, dyes and tanning?
These are the parts brands rarely discuss. Ask what adhesives hold the shoe together and how any leather is tanned (chrome-tanned leather has its own testing requirements). Water-based or low-solvent adhesives and plant-based tanning are good signs.
6. Which certifications actually mean something?
Not all labels are equal, and none is a complete guarantee.
- CPSIA / Children’s Product Certificate (CPC): the US legal requirement for children’s products, backed by third-party testing at a CPSC-accepted lab. It confirms compliance with the rules that apply, which for shoes means lead but not federal phthalate limits. Ask to see the actual test report, not only the logo.
- Oeko-Tex Standard 100: a widely used textile safety certification. Useful, but see the PFAS caveat above.
- GOTS: certifies organic textiles; relevant to cotton linings and uppers, not whole shoes.
- REACH (EU): European chemical regulation; brands made in Europe typically work within it.
- “Non-toxic,” “eco-friendly,” “clean”: unregulated marketing terms on their own. Treat them as a prompt to ask for evidence.
Don’t forget the fit
A shoe can be chemically spotless and still be wrong for a growing foot. A paediatric review of children’s footwear recommends flexible shoes with enough room for the toes, and warns against narrow or pointed toe boxes. Safe materials and a good fit are not a trade-off, and you should expect both.
10 questions to ask any kids’ shoe brand
- What are the upper, lining, insole and outsole made of?
- Is there any PVC or vinyl, including in straps, charms or decorations?
- Do you test for phthalates? Can I see the report?
- Do you test for lead and heavy metals?
- Is any waterproofing or stain-resistant finish PFAS-free, and how do you know?
- What adhesives do you use?
- How is the leather tanned?
- Which lab tests the shoes, and can I see your Children’s Product Certificate?
- Where, and by whom, are the shoes made?
- What happens to the shoe at the end of its life?
Red flags
- Materials described only as “synthetic,” “man-made” or “performance fabric”
- “Non-toxic” with no test report or certificate to back it up
- “Waterproof” with no statement about PFAS
- A strong chemical smell out of the box
- No information about where or how the shoes are made
How we approach it at Little Fierce
I started Little Fierce because I couldn’t find shoes that answered these questions, so we built our own around them. Our shoes are handmade in a family-run factory in Porto, Portugal, from plastic-free, phthalate-free, plant-based, biodegradable materials, and every style is CPSIA tested. Safety comes first, craftsmanship second, and the fact that they’re biodegradable proves that being kind to the earth is also protecting our children. You’re welcome to ask us any of the ten questions above. My DMs are open on Instagram at @heylittlefierce
