Orders

How do I place an order?

Choose your size (US / EU / UK/ JP) and colorway, add to cart, then check out with our secure payment gateway.

Can I edit or cancel my order?

Yes—click “Manage Order” in your confirmation email.

Do you offer half sizes?

Please refer to Fitasy Size Chart for more details. If you’re between sizes, we recommend going up half a size. 

Can I buy gift cards or place a team order?

For corporate or group orders, email sales@fitasy.com

Returns & Exchanges

Return window?

Return or exchange any undamaged pair within 30 days of delivery. The shoes need to be returned with original packaging and in unworn condition. 

How do I start a return / exchange?

Log in → Orders → “Return / Exchange,” print the prepaid label, drop it at any listed courier.

What if the fit feels off?

We’ll swap for another size for free. If it still doesn’t work, you’ll receive a full refund.

How long does it take to process the refund?

Refunds are processed within 5 business days after we receive your return.

Do you really recycle worn-out pairs?

Yes—send them back when it’s worn out (with damage to the lattice structure) and get 10 % credit toward your next order. We grind the mono-material and remake it into other industrial products like running track. Please contact info@fitasy.ai to arrange your trade-in.

Shipping & Delivery

Where do you ship?

We ship worldwide. Shipping cost is calculated at checkout based on your location and chosen service.

How long does it take to deliver?

Domestic (USA) Delivery: 3-5 days. International delivery timeline will depend on the courier option selected. A real-time ETA shows before payment.

What are the shipping cost?

Standard shipping is free on orders ≥ USD 150; express options are offered at carrier rates.

Can I track my order?

A tracking link and milestone emails/SMS arrive once your pair leaves the print hub.

Product Information

What makes Fitasy shoes different?

Each pair is built with precise 3-D engineering for optimized comfort—one ingredient, one print, endless possibilities.

Material used?

High-rebound PU (polyurethane) printed in a single uninterrupted run—no glue, no waste—yielding a lattice that tunes cushioning zone-by-zone.

Breathability?

Open-lattice geometry provides 360° airflow and quick-dry performance, similar to adidas Climacool shoes that use full-foot ventilation and drainage ports for rapid moisture release  .

Water use?

Not waterproof but water-friendly: the lattice drains quickly, making them ideal for beach, boat, or light water activities.

Care instructions?

Rinse with warm water & mild soap, then air-dry. Avoid soaking > 24 h or exposing to direct sun / high heat > 48 h to protect the PU lattice.

Wide widths?

Launch models are regular width; wider/narrower fits are planned—join the newsletter for updates.

How should I wear my Fitasy shoes?

Fitasy shoes like Stride and our other sneakers are designed to support your lifestyle—whether you’re recovering after a workout, standing all day, walking through the city, or enjoying light training or water-friendly activities.

 

For short-duration use, it’s perfectly fine to wear them without socks—they’re breathable, soft, and skin-friendly.

 

However, for longer wear, we recommend pairing them with socks or a heel pad. This helps protect your skin from friction at the edges, especially during extended walking or standing.

 

Fitasy shoes are crafted for versatility, comfort, and style—but your comfort also depends on how you wear them!

3-D Printing

What printing technology do you use?

High-speed resin-based SLA/DLP printing technology.

Print time per pair?

Full print ranges between 1.5-5 hours depending on the product; full production (print + finish + QA) is 5 – 7 days.

Is the tech eco-friendly?

3D printing can cut greenhouse gas emission of footwear manufacturing by ~48% and reduce water consumption by 99% compared with traditional footwear manufacturing, according to study by Portland’s HILO, in partnership with Yale’s Centre for Business and Environment. 

Lattice Design & Comfort Technology

What is a lattice structure in footwear?

A 3-D web of struts whose geometry varies across the shoe to absorb impact and propel you forward.

Why lattice over foam?

Foam is uniform; lattice lets us tune cushioning zone-by-zone for soft landings and springy toe-off. EVA foam is soft and flexible at first, but can quickly become 'dead foam', while 3D printed lattices are designed to maintain the cushioning over time even under repeated stress.

Durability?

  • Engineered Resilience: 3D printed lattices made from elastomeric polyurethane or similar resins (such as those used by Adidas and Carbon) are designed to maintain their structure and elasticity over time, even under repeated stress.
  • Fatigue Resistance: Lattice structures distribute and absorb impact more efficiently, reducing localized stress and minimizing permanent deformation.
  • Long-Term Performance: User reports and durability studies indicate that 3D printed lattice midsoles retain their cushioning and responsiveness for well over 1,000 km of use, with minimal breakdown compared to EVA-based shoes. The open lattice design also prevents the bottoming-out effect common in traditional foams, based on studies conducted by Carbon and Adidas.
  • Customizability: The lattice structure can be digitally tuned for different zones of the shoe, optimizing both comfort and durability in a way not possible with uniform EVA foam.

Sustainability

How sustainable are Fitasy shoes?

On-demand printing eliminates inventory waste; one mono-material enables full recyclability.

“One ingredient, one print” meaning?

Each shoe is printed in one continuous run from a single material—no adhesives or multi-part assembly.

Eco-friendly packaging?

100 % recyclable boxes printed with water-based inks.

Return old shoes for recycling?

Yes—ship them back free; we grind and remelt the material for other industrial goods like running tracks. You can trade-in your shoes to get a discount on your next pair!
