PRODUCT INFO
Every component in your QLVR Running Slipper challenges convention. From our bio-based materials to our women-first design approach, each innovation serves a purpose: to deliver performance footwear that truly understands you.
At QLVR, every curve, every component, every detail serves a purpose. Our design philosophy is simple: create performance footwear that works in perfect harmony with women's biomechanics. No decorative flourishes, no unnecessary elements – just pure, purposeful design that delivers.
Traditional athletic shoes start with men's lasts and scale down. We started fresh, creating a design that's built around the unique triangular shape of women's feet. Higher arches, wider toe boxes, narrower heels – every aspect of female foot anatomy informed our design process.

FIT & SIZE GUIDANCE
QLVR Footwear runs true to size and based on a regular width fitting (not a wide fitting). Please note that our women's specific shape intentionally delivers a snug 'locked-in' fit around the heel and across the instep.
The QLVR Wing fit system is moulded in a closed 'laced-up' position and thanks to the Pebax material, it will maintain this locked-in feeling throughout wear. Go with your true size to get that snug locked-in feeling or if you prefer a more loose feeling, you could go up a size.
The 'Foot Length' measurements which you can find below relates to the length of your foot from the back of your heel to your longest toe. You don't need to go up a size for 'toe wiggle room' as this is already built in.
How to measure your foot length:
- Tape a piece of paper to the ground or a flat surface, ensuring the paper doesn't slip.
- Stand on the paper, feet shoulder width apart only one foot on the paper.
- With a pen or pencil pointed straight down, draw around the toes and around the outermost part of the heel.
- Once done, step off the paper and use a ruler or tape measure to measure the distance between the tip of the longest toe and the back of the heel. This measurement represents the 'Foot Length'.
- Repeat this process with the other foot. It is common for one foot to be a slightly different in length to the other foot.
- Apply the longer of the two measurements to our size chart above to find the right correlating size for the recorded foot length. If the measurement is between sizes, we recommend sizing up half a size.
CARE GUIDANCE
You can wash your QLVR. Just follow the below steps:
- Remove in-soles
- Place shoes in a mesh laundry bag (or a pillowcase).
- Wash on a gentle cycle with COLD water & mild detergent.
- Gently re-shape and leave to air dry.
- Shoes will regain their original shape the next time you wear them.

FREQUENTLY ASKED QUESTIONS
Please read our FAQs page to find out more.
Where do you ship to?
We ship QLVR worldwide.
How do they work?
Our patented QLVR wing fit system is designed in a closed ‘laced up’ position, so that once it is on it will instantly give you a secure ‘locked in, laced up’ feeling. The 360 degree zig zag system provides a secure fit all around your foot and yet it can flex to mould to the shape of your foot. The narrower heel design ensures better heel hold to prevent heel slipping and stop your foot from moving back and forth inside the shoe.
So to put the shoe on, you place your foot on the rear of the wing (stepping on the back of your shoes like kids do!) and this opens the shoe for you to step in. Then to remove your foot you step the other foot on the rear kick step (see demo videos) which opens the shoe to remove your foot..
How do I choose my size?
Go with your true size to get that snug locked-in feeling. If you prefer a more loose feeling, or if you like to wear thick socks, go up a size.
As footwear brands’ vary in sizing, we recommend that you measure your foot length following these instructions here.
Why do you supply 2 extra insoles in the box?
We know that some athletes prefer a tighter fit for performance days and a more roomy fit for off duty or leisure wear. So we include 2 different thickness insole options in every box so you can select your ideal fit. Our built in insole also offers extra cushioning and the flexibility to wear personalised orthotics.
Are QLVR made with sustainable materials?
Yes. You can see the full breakdown of the materials here.
Our goal at QLVR is to build the best performance products but use materials that do the least amount of harm to our environment. With this in mind we are working with innovative companies to utilise their Premium Sustainable Materials and Compounds within our products.
The QLVR Running Slipper is crafted with premium sustainable materials, ensuring a responsible choice. The foam compound is derived from dandelions, providing a lightweight and responsive feel. Our bio based premium rubber sole is made from corn cob waste offering durability and slip resistance. Additionally, we use Pebax® Rnew® bio based polymer made from castor beans to make our QLVR wing and our spring plate, adding a high-performance element to the trainers. QLVRs also feature Tencel yarn, woven from Lyocell fibers derived from sustainably grown eucalyptus wood. These materials not only make the Running Slipper sustainable, but also ensure they are durable, comfortable, and high-performing.
