Frequently asked questions

About the footwear
How do I find my correct size?
Each product page includes a full size guide with UK, EU, and US conversions. Sizing can vary between styles and brands, so we recommend measuring the length of your foot in centimetres and matching against the guide. If you're between sizes, we generally suggest sizing up for a more comfortable fit. Our team is happy to advise before you order — just get in touch.
Are the shoes comfortable for all-day wear?
Comfort is one of our key selection criteria. We look for cushioned insoles, supportive footbeds, and heel heights that are elegant without being punishing. Product descriptions include heel height measurements and notes on sole type so you can make an informed choice. If you have any specific comfort requirements, feel free to reach out before ordering.
What materials are the shoes made from?
Full material details — upper, lining, and sole — are listed on each product page. Our collection includes genuine leather, suede, and high-quality synthetic options. We select materials for their appearance, durability, and how well they hold up with regular wear.
How should I care for my footwear?
Care varies by material. Leather shoes benefit from a regular wipe with a damp cloth and occasional conditioning to maintain suppleness. Suede should be brushed with a suede brush and kept away from water — use a protective spray for best results. Store shoes in a cool, dry place away from direct sunlight, ideally in their original box or a dust bag to retain their shape.
Orders & service
What is your returns policy?
We offer a straightforward 30-day returns policy. If the fit isn't right or you're not completely satisfied, contact our team with your order number and we'll guide you through the process. Please ensure shoes are returned unworn with the original packaging intact. Refunds are issued within 5 working days of receiving your return.
When will my order arrive?
Orders placed today are dispatched the next working day. All deliveries include full tracking so you can follow your parcel every step of the way. Free UK delivery is included on every order, with no minimum spend.
How do you ensure the quality of your footwear?
Every pair in the Koossa collection is personally selected for its construction, comfort, and finish. We assess sole durability, stitching quality, and how each shoe wears over time — not just how it looks on first impression. If it wouldn't meet our own standards, it won't reach yours.
Why shop with Koossa for footwear?
Koossa footwear is curated for women who want shoes that are as comfortable as they are beautiful — pieces that carry you through your day with ease and style. Every order comes with free UK delivery, a 30-day returns window, and genuine customer care. Because finding the right pair should be effortless.

Our Promise

Every pair is chosen to last

A beautiful shoe should also be a comfortable one. Every pair in the Koossa collection is personally selected for its construction, materials, and how it actually feels to wear — not just how it looks in a photograph. We assess sole quality, lining comfort, and long-term durability before anything reaches you. If it wouldn't meet our own standards, it won't reach yours.
