GUCCI SIZING
If you are eyeing a pair of pristine pre-owned Gucci Ace or Gucci Rhyton sneakers from NASS, you need to exercise caution with the size labels.
Unlike typical sports brands, Men's Gucci sneakers use a unique luxury metric stamped right onto the shoe's tongue. To find your standard US fit, always go up one half-size from the stamped Gucci number. For example, if you see a stamped size 10, it converts directly to a standard US Men's 10.5. Because silhouettes like the Gucci Ace are built with a slightly generous footbed, a converted US 10.5 will also comfortably fit anyone who normally wears a slim or standard US Men's 11.

💡 Rhyton vs. Ace: How They Actually Fit on Your Feet
Beyond raw conversion numbers, the structural silhouettes of these two iconic sneakers heavily alter their physical fit:
- The Gucci Ace (Low-Top Slim Silhouette): The Ace is constructed with premium, rigid calfskin leather and features a slightly narrower, elongated toe box. While the general length runs about a half-size large, customers with wider feet should buy their true stamped Gucci size from the table above to avoid pinching. If you have narrow feet, you can safely size down a half-step further.
- The Gucci Rhyton (Chunky Dad-Shoe Silhouette): The Rhyton is famous for its heavily padded collar, thick statement midsole, and exceptionally plush interior. Because of the bulky construction and wide base, the internal footbed is incredibly roomy. The specialists at NASS recommend going one half-size down from your usual sneaker size for the optimal, locked-in fit.
Before pulling the trigger on luxury footwear, we highly recommend checking the physical label measurements of your best-fitting shoes or reaching out to our customer care team at NASS for an exact insole measurement!
