BIRKENSTOCK Cork Thong EVA New Style Size 36-45 Flip Flops Thong Sandals A85

First Impressions: The Birkenstock Cork Thong EVA

The Birkenstock Cork Thong EVA (style A85) is a lightweight, waterproof take on the classic cork sandal. Unlike the traditional leather-and-cork models, this thong uses a synthetic EVA upper and an EVA outsole, making it ideal for beach, pool, or rainy days. But does it deliver the same orthopedic support? Let's compare it to the original Birkenstock sandals you know.

Comfort and Support: Cork Footbed Meets EVA Flexibility

The biggest selling point of the Cork Thong EVA is its contoured cork footbed. Yes, it's real cork layered over a latex core, just like the classic Arizona or Milano. The deep heel cup, arch support, and toe grip are all present. The difference is the EVA outer layer, which adds a slight cushion and waterproofing. The straps are soft, non-chafing EVA that flex with your foot. Compared to original Birkenstocks, the Cork Thong EVA feels slightly lighter and more forgiving, but still offers the same pronation control. If you love Birkenstock support but hated the break-in period, this is a plus.

How Does It Compare to Original Birkenstocks?

• Durability: Original Birkenstocks with leather straps can last decades with resoling. The Cork Thong EVA is more disposable; the EVA straps may crack after 2-3 years of heavy use. The cork footbed is still replaceable, but the upper is not.
• Wet Use: The EVA construction means you can wear these in water without damage. Original Birkenstocks (even with Birko-Flor) should not be soaked. The Cork Thong EVA dries quickly and won't stain.
• Break-In: Original Birkenstocks require a few weeks to mold to your feet. The Cork Thong EVA is comfortable from day one because the EVA is more pliable. However, the cork footbed still adapts over time.
• Aesthetic: The Cork Thong EVA has a chunkier, sportier look. The thong strap is wider and more modern. Available in solid colors only (black, white, navy, etc.) vs original's varied materials and prints.

Sizing: Does It Run True to Size?

Birkenstock sizing can be tricky. The Cork Thong EVA is available in sizes 36 to 45 (European). In our experience, it runs slightly larger than original Birkenstocks. If you wear a US 8 in Birkenstock Arizona, order a size 37 or 38 in the Cork Thong EVA? We recommend trying them on or measuring your foot length in cm. The footbed is identical in shape to classic Birkenstocks, so if you already know your Birkenstock size, order the same. But note: the EVA straps have less adjustability, so if you have narrow feet, you may find them loose. For wide feet, the stretchy EVA accommodates nicely.

Width Options

Unlike many Birkenstock models, the Cork Thong EVA comes only in regular/wide width. There is no narrow version. The footbed is the same width as a standard Birkenstock regular (102 mm at the ball for size 38). If you normally wear narrow, consider sizing down half a size or trying an insole.

Price and Value: Worth $69.88?

Retailing at $69.88, the Cork Thong EVA is cheaper than most leather Birkenstocks ($100-$160) but more expensive than all-plastic flip-flops ($10-$30). You're paying for the cork footbed, which is the same as the $130 models. The trade-off is reduced longevity. If you wear flip-flops exclusively at the beach and expect to replace them every year or two, the Cork Thong EVA offers exceptional comfort for the price. If you want a shoe that lasts a decade, stick with the original leather Birkenstocks and keep them dry.

Who Should Buy the Cork Thong EVA?

• Birkenstock loyalists who want a waterproof option for summer activities.
• People with foot pain (plantar fasciitis, flat feet) who need support in a thong style.
• Travelers who need a lightweight, packable sandal that can handle both walking tours and poolside lounging.
• New Birkenstock wearers who want to try the footbed without a big investment or break-in period.

Who Should Skip?

• Eco-conscious buyers concerned about EVA plastic's environmental impact. (Cork is renewable, but EVA is synthetic.)
• Long-term minimalists who prefer a single pair of sandals for all purposes.
• Narrow-footed individuals who need adjustable straps and a narrow fit.

Final Verdict

The Birkenstock Cork Thong EVA is a solid, comfortable thong sandal that merges Birkenstock's iconic orthotic support with modern materials. It's not a replacement for the original line, but an excellent addition for specific uses. If you value waterproof convenience over heirloom durability, this is your sandal. Just be honest about how often you'll wear it and whether you prefer the classic aesthetic. For the price, it's a fair trade.
