Frequently Asked Questions

Everything you've ever wanted to know about SHOES 53045 (and then some)

How does your sizing work?

Our sneaker-shoe hybrids are unisex.

We offer Euro unisex sizes from 35 to 45. We don’t do half sizes.

See our size chart here.

All product pages include a size chart to help you find your own Euro size.

For your comfort, we provide an extra pair of insoles with each box.

Swap these in for a more snug fit.

How does the Bump’air fit?

We have found we tend to run a half (Euro) size bigger. If you are a half (Euro) size, most customers size down (example: if you are 38.5, we recommend you take a 38). However, you have a wider foot and you are a half size, we would suggest sizing up (example: you are 43.5, and we’d recommend you take a 44).

If you are a full size, we recommend you stick with your size. The extra pair of insoles in your package can be swapped in for a more snug fit.

Still not sure? We are here to help! Reach out to one of our fit specialists at for personalized advice.

Are the insoles removable?

Yes! The insoles are removable on all our Bump’Airs.

For your comfort, we provide an extra pair of insoles in each box.

Swap these in for a more snug fit.

What is SHOES 53045?

We are a digital native footwear brand sent from the future (but we took a detour through the ’90s).

We’re creating a new generation of footwear: sneaker-shoe hybrids with platform bubble air soles and a dose of fun.

We are based in Los Angeles. Our shoes are designed in Paris and handcrafted with luxury high quality materials by athletic technology experts in China.

By selling directly to you, we can offer incredible value for the quality.

What does 53045 refer to?

53045 reads SHOES upside down in a digital font. Look at your calculator!

How do you deliver such high quality at prices much lower than the other luxury sneakers?

By focusing on selling direct-to-consumer and cutting out the inefficient retail model with its 2.5x markup, we can create great shoes and sell them to you for less.

Why do you choose to manufacture your shoes in China?

China is the best country for the most high-tech sneakers—in the same way that other countries have their specialties (like Italy’s leathergoods tradition, Spain’s handcrafted espadrilles, Morocco’s straw, Indian embroidery).

Our factory handcrafts the most complicated sneakers to perfection.

What is the composition of your Bump’Air?

   • Upper: Polysynthetic leather 82%, Thermoplastic polyurethane 6%. Fabric 12% Midsole: Thermoplastic polyurethane 100%

   • Outsole: Thermoplastic rubber 100%

   • Insole: Foam / Mesh

   • Lace: Nylon 100%
