Product overview
About smart-casual rubber-sole shoes
Smart-casual rubber-sole shoes take a derby or chukka upper and put it on a lighter, more relaxed sole: crepe, gum or a light rubber unit. Suede and soft leathers are typical.
The construction can be cemented for lightness or stitched for a more crafted look. The last is usually more generous than a formal last, with a rounder toe.
OEM: your design
Send your pattern and sole reference. We match last and sole and sample in your leathers.
ODM: developed with you
Share references; we propose upper style, leather and sole and develop through samples.

- 02Mark the tip of the longest toe and measure from the wall to the mark in millimetres.
- 03Measure both feet and use the longer one; measure later in the day when feet are largest.
- 04Compare with the foot-length column, not the shoe's outside length.

Testing and compliance
Frameworks relevant to this style. Obligations depend on where and how the product is sold, and the brand placing it on the market carries them. General information, not legal advice.
EU REACH restrictions (Annex XVII)Market obligation
Restricts chemicals in articles sold in the EU, including chromium VI in leather in contact with skin (entry 47, limit 3 mg/kg), certain azo dyes, PAHs in rubber parts and dimethyl fumarate. Leather and component suppliers' test reports are collected per order where a buyer requires them.
EU footwear labelling (Directive 94/11/EC)Market obligation
Footwear sold in the EU must indicate the material of the upper, the lining and sock, and the outsole, using the directive's pictograms or wording. Labels are produced to the buyer's market requirements.
EU General Product Safety Regulation (EU) 2023/988Market obligation
Applies since 13 December 2024 to consumer products placed on the EU market, including traceability information on the product or packaging. The obligations sit with the economic operator placing the product on the market; we supply the production information they need.
UK footwear composition labellingMarket obligation
The UK keeps equivalent requirements for indicating the composition of upper, lining and sock, and outsole on footwear sold to consumers.
Physical test methods (ISO footwear methods)Optional test, on request
Commonly requested tests include whole-shoe upper-to-sole adhesion (ISO 17708), outsole abrasion (ISO 20871), outsole flex resistance (ISO 17707), upper flex resistance (ISO 17694) and colourfastness of footwear components (ISO 17700). Tests are run by external laboratories on request; no results are published until reports exist.

Chromium VI (EN ISO 17075), formaldehyde and pH testing of leather can be arranged with the tannery or an external lab for buyers who require reports.
Khairay Footwear does not state any certification, approval or test result for this style unless documentation exists for your order.
Sampling, quality control and shipping explainedFAQ
Smart-Casual Rubber-Sole Shoes: questions buyers ask
Is this a derby or a chukka?
Either. The upper style is chosen in your brief; both work on crepe or rubber soles.
Can you use natural crepe?
Natural crepe soles are available from specialist suppliers, confirmed at the brief stage.
Can the sole be stitched?
Stitched constructions are possible subject to feasibility; cemented is typical.
Suede or leather?
Both; suede is the classic choice for this style.
What do you need to quote?
Upper style, leather, sole, size range, quantities and branding.
Can we combine several casual styles in one order?
Yes. Styles sharing leathers or soles can be planned together, which helps with material minimums. Each style still has its own size breakdown.
What information do you need for a casual-shoe quotation?
References or a tech pack, leather and sole preferences, size range, quantity per colour, branding and packaging requirements, and your destination market.
Can we submit our own design instead of this reference?
Yes. This page is a reference only; the RFQ accepts your own design files, sketches and samples without choosing a reference style.
