Welcome to the Birkenstock Cork Thong EVA New Style A308 FAQ. This page answers the most common questions shoppers have before buying these iconic slip-on sandals. Whether you're concerned about sizing, materials, or how to care for them, we've got you covered.
The Cork Thong EVA is not your average flip flop. It features a contoured cork footbed that molds to your foot over time, offering exceptional arch support and orthopedic benefits. The EVA outsole provides lightweight cushioning and flexibility, making these sandals ideal for all-day wear. Unlike cheap foam flip flops, the Birkenstock design promotes proper posture and reduces foot fatigue.
These sandals should fit snugly but not tight. Your toes should not overhang the front edge, and your heel should sit comfortably in the heel cup. The cork footbed will conform to your feet after a break-in period, so expect a personalized fit. If between sizes, we recommend sizing up for a more comfortable fit, especially if you have wide feet.
The Birkenstock Cork Thong EVA A308 is available in European sizes 36 to 45. This includes women's sizes 36-42 and men's sizes 39-45 typically. Refer to our size chart to convert to US or UK sizes. The thong strap is adjustable via a pin buckle, allowing for a custom fit across the instep.
Yes, the Birkenstock Cork Thong EVA is highly recommended for flat feet and plantar fasciitis sufferers. The firm cork footbed provides excellent arch support and deep heel cup, which helps stabilize the foot and reduce strain on the plantar fascia. Many customers report significant relief from foot pain after switching to Birkenstocks.
The EVA outsole is water-resistant, but the cork footbed is not. If the cork gets wet, it can become soft and lose its shape. We advise avoiding prolonged water exposure. If they do get wet, let them air dry away from direct heat. For beach or pool use, consider the all-EVA Birkenstock models.
These sandals come in a variety of colors, from classic black and white to vibrant hues. Neutral colors like black, brown, or tan are versatile and go with most outfits. Bright colors like fuchsia or turquoise make a statement. Consider your wardrobe and intended use—neutral for everyday, bold for vacation.
The break-in period varies from person to person but typically takes 1-3 weeks of regular wear. Start by wearing them for short periods (a couple of hours) and gradually increase. You may experience some initial discomfort as the cork molds to your feet. Once broken in, they become incredibly comfortable.
Clean the cork footbed with a slightly damp cloth and mild soap if needed. Avoid soaking. For the EVA outsole, wipe with a damp cloth. Never machine wash or dry. Use a cork sealer occasionally to keep the cork from drying out. Store them away from extreme temperatures and direct sunlight.
Absolutely! They are lightweight, comfortable for walking, and easy to slip on and off. Perfect for airports, hotel rooms, and casual sightseeing. The thong design is compact and packable. Plus, they provide better support than most travel sandals.
With proper care, these sandals can last several years. The cork footbed is durable yet flexible, and the EVA outsole resists wear. Some customers report wearing them daily for 3-5 years before needing replacement. The leather straps also hold up well if properly maintained.
No, the footbed is not replaceable on this model. The cork footbed is bonded to the EVA outsole. When the footbed wears out, it's time for a new pair. However, with proper care, the cork can remain supportive for years.
The A308 is the Cork Thong EVA with a classic thong strap and adjustable pin buckle. The A315 (similar style) may have a different footbed or strap material. Always check the exact model number for features. The A308 is part of the 'New Style' line with a sleeker profile.
Some customers report a slight slapping noise, especially if the sandals are loose. A proper fit reduces noise. The EVA outsole is quieter than leather soles. If noise is a concern, ensure your sandals fit securely and break in the cork footbed.
Yes, the Birkenstock Cork Thong EVA A308 is a unisex style. The design is simple and works for all genders. Sizes 36-45 cover both women's and men's ranges. The thong strap and neutral color options are suitable for anyone.
The buckle is a standard pin buckle. Simply lift the buckle tongue, slide the strap to the desired length, and press the tongue back down. Make sure the strap is not too tight or too loose. A good fit allows one finger to slide under the strap.
Yes, the contoured footbed supports high arches as well. The arch support is pronounced, which may feel different initially but offers excellent alignment. If you have very high arches, the footbed may feel supportive rather than uncomfortable after a short break-in.
Birkenstock offers a 2-year warranty against manufacturing defects. This does not cover normal wear and tear, including footbed compression, strap wear, or damage from improper use. Keep your receipt for warranty claims.
Absolutely! Many people wear socks with Birkenstocks for style or comfort. Choose thin or toe socks to maintain a better fit. This can also help during the break-in period to reduce friction.
Birkenstock sandals are primarily made in Germany, though some components may be sourced elsewhere. The A308 is manufactured in Germany to ensure quality and craftsmanship.
Authentic Birkenstocks have a distinct cork footbed, a Birkenstock logo embossed on the footbed, and a model number (A308) on the sole. The packaging includes a care leaflet. Purchase from authorized retailers to guarantee authenticity.
Yes, once broken in, these sandals are comfortable for long hours of walking or standing. The cork footbed provides cushioning and support, while the EVA outsole absorbs shock. Many people wear them as their go-to summer sandal.
If loosening occurs, try tightening the buckle. You can also add a small heel grip or insole for a snugger fit. If they are significantly loose, you may need a new pair with a smaller size. The cork will compress over time, so a snug initial fit is best.
No, the Birkenstock footbed is designed to be used as is. Adding insoles may alter the fit and support. The built-in arch support is usually sufficient for most feet. If you need custom orthotics, consult a podiatrist.
Birkenstock uses natural cork from sustainably harvested cork oak trees. The EVA outsole is recyclable in some programs. The brand is committed to reducing environmental impact, but check specific product details for certifications.
Please check our return policy. Typically, unworn sandals in original packaging can be returned within 30 days. Customized or worn sandals may not be eligible. We recommend trying them on indoors on clean surfaces to determine fit.
Store them in a cool, dry place away from direct sunlight. Use a shoe tree or stuff with tissue paper to maintain shape. Keep them in a dust bag or box when not in use. Avoid stacking heavy objects on top.
Wear them for short periods daily, gradually increasing time. Wiggle your toes and bend your feet to help the cork mold. If you experience blisters, use bandages or wear socks temporarily. The cork will soften with body heat and become more pliable.
Yes, but sizes start at 36 (roughly US women's 5/6). For children with smaller feet, consider Birkenstock's kids' line. The arch support is beneficial for growing feet, but ensure a proper fit for safety.
Yes, the thong strap adjusts to accommodate wider feet. The footbed is the same width as regular Birkenstock models. If you have very wide feet, you may need to size up or try the 'Unisex' wider fit version. The A308 is standard width (regular).
The strap is made of Birko-Flor or leather depending on the variant. For Birko-Flor (synthetic), wipe with a damp cloth. For leather, use a leather cleaner and conditioner. Avoid harsh chemicals. Let them air dry completely.
They are lightweight, typically weighing around 8-10 ounces per sandal for a women's size 38. The EVA outsole contributes to the light feel, making them easy to pack and wear.
Not from the factory. However, some cobblers may replace the strap or buckle. This will void the warranty. Birkenstock does not offer customization for this model.
No, never machine wash. Water and agitation can damage the cork footbed and straps. Spot clean only.
No, they are only available in full EU sizes. If you are between sizes, it's generally recommended to size up. For example, if you are a US women's 7.5 (EU 38.5), choose size 39.
