Puma Speedcat OG Dark Myrtle White: how to choose the right size and style

The Puma Speedcat OG Dark Myrtle White stands out with its low-profile shape, dark green colour and white details. The sneaker takes inspiration from classic Puma racing shoes, but is designed primarily as a casual sneaker for everyday wear and streetwear. If you’re buying online, there’s more to consider than just the colour. Fit, materials and care all help determine whether this Puma Speedcat OG is right for you.

Common pitfalls when buying retro sneakers

1. Mistaking a narrow, low-profile shape for a roomy fit

The Speedcat has a streamlined silhouette, a rounded toe and a flat heel. This gives the shoe a retro look, but it doesn’t mean every foot will have the same amount of room. The product information lists a regular fit. So, check your usual EU size and, where possible, compare it with a pair of sneakers that fits you well.

Pay attention to the lacing, too. Lace-up sneakers let you adjust the pressure around your instep more easily than slip-on styles. This can be useful if you’re between sizes, but it’s no substitute for checking a reliable size guide.

2. Assuming “leather” means no maintenance

The Puma Speedcat OG Dark Myrtle-White 398846-12 has a leather upper, a textile lining and a rubber sole. Leather can enhance the look of the sneaker, but it needs care. The product instructions recommend waterproofing the shoes before wearing them.

Avoid soaking them for long periods and don’t dry the sneakers directly on a radiator. You can usually remove dirt gently with a soft, slightly damp cloth. Always check the manufacturer’s instructions before using a cleaning product.

3. Assuming racing heritage makes it a sports shoe

The Speedcat is inspired by motorsport and is associated with racing culture in the product information. That makes it an appealing style for fans of retro racing looks. However, it’s not automatically suitable for running, intense gym sessions or prolonged sporting activity. For these, shoes designed for the activity, with the right tread, cushioning and breathable technical uppers, are a better choice.

Key specifications to check before you buy

Upper and lining

For the green version, the product specifications list leather as the upper material. The lining is textile. This distinction matters: the lining may feel different from the outer material and can affect how the shoe feels during everyday wear.

If you’re specifically looking for leather Puma sneakers, always check the material details for the colour and size you’re interested in. Different versions with the same model name may have different materials listed.

Sole construction

According to the product information, the midsole and outsole are made of rubber. The manufacturer also lists IMEVA as a material that provides a lightweight, comfortable feel. As this is a brand-specific term, it’s best to treat it as PUMA’s description rather than an independent guarantee of a particular level of comfort.

The outsole has a flat profile and a rubber composition, in keeping with the low-profile retro shape. On wet streets, it’s still important to walk with care; no sole can make a slippery surface automatically safe.

Size and fit

Available versions of the Puma Speedcat 398846-12 include EU sizes 37, 37.5, 38, 38.5, 39, 40, 40.5 and 42. The product description lists a regular fit. Start with your usual European size, but check:

  • whether your feet need more room at the end of the day;
  • whether you plan to wear the sneakers with thin or thicker socks;
  • whether you prefer extra room around the toes;
  • whether the instep feels comfortable when the laces are tied.

The green colour is listed as Dark Myrtle-PUMA White. Search results may also use “green and white Puma sneakers” or “Puma Speedcat OG Dark Myrtle” for the same colourway. So, always check the product number 398846-12.
