NK R4 Leather Caged Runner
Retro engineering meets street style.
A leather-caged runner built around a visible column sole for that unmistakable retro-tech look. Durable leather panelling wraps the foot while the perforated toe and heel keep things breathable, making this a low-top that pairs comfort with heritage running design.
- Visible column-style midsole for a bold, layered profile
- Leather upper with perforated detailing for breathability
- Padded collar and cushioned tongue for all-day wear
- Pair with joggers or straight-leg denim for an off-duty look
- Available in multiple colourways to suit your rotation

Top-tier quality for the price!
I ordered the RL Essential Set and honestly didn’t expect it to feel this premium. The fabric is soft, fits perfectly, and the attention to detail is incredible.
Exactly what I was looking for.
The TNF Puffer Jacket keeps me warm without being too heavy. It looks sleek and feels way more expensive than it costs. Shipping was also fast and hassle-free.
Comfort and style combined.
Got the Ralph Lauren Prestige Collection — super comfortable and elegant. Perfect for lounging or casual days out. Everyone keeps asking where I bought it.
Better than I expected!
I was skeptical at first, but the UA Waterproof Jacket exceeded my expectations. Great quality, fits true to size, and actually waterproof. Will definitely order again.
Classic look, modern comfort.
The RL Polo Hampton Collar Shirt feels timeless. The cut is flattering and the fabric quality is top-notch. You can really tell this brand focuses on style and comfort.
Great deals and great service.
I got two items during the sale — both arrived quickly and were exactly like the pictures. Saint Martin is now one of my go-to stores for quality menswear at fair prices.
