Birkenstock vs Taos Sandals: Arch Support and Fit

Arch support design: cork vs contoured footbed

The main difference between Birkenstock and Taos sandals is the footbed. Birkenstock uses a cork footbed that is rigid and firm, with a pronounced arch support and a deep heel cup. The cork is layered over a flexible base and covered with suede. Over time, the cork compresses and molds to the shape of your foot, creating a custom fit. This is why Birkenstock wearers often describe the break-in period as necessary.

Taos uses a contoured footbed made of a cushioned foam or EVA material that has built-in arch support and a heel cup. The contour is designed to support the natural shape of the foot, but the material is softer than cork. It provides immediate comfort without a break-in period. If you want arch support but prefer a cushioned feel underfoot, Taos is the more forgiving choice.

• Birkenstock: firm cork footbed, molds over time, needs break-in.
• Taos: soft contoured footbed, immediate comfort, minimal break-in.

Fit and sizing: how each brand runs

Birkenstock sandals typically run true to size but fit differently from most shoes because the footbed is shaped like a footprint. Your foot should sit inside the raised edges of the footbed, not hang over. If you are between sizes, many wearers size up, especially if you have wide feet. The straps can be adjusted, but the footbed shape is fixed.

Taos sandals generally run true to size and have a more conventional fit. The footbed is flatter at the edges, so your foot does not need to sit inside a raised rim. This makes Taos easier to fit for people with wider feet or those who prefer a looser feel. The straps are adjustable on most styles, but the overall fit is more like a typical sandal than Birkenstock’s structured footbed.

Both brands offer half sizes in some styles, but not all. For a more precise fit, measure your foot length and width before ordering. See our guide on how to measure foot size for the correct method. Also, try sandals on later in the day when your feet may be slightly swollen, as this gives a better sense of the fit you will experience during regular wear.

Support and comfort for different foot types

Arch support is not one-size-fits-all. People with high arches may find Birkenstock's firm arch too aggressive, while people with flat feet might need more structure. Taos's softer contour is more neutral and works for a wider range of foot types. If you have plantar fasciitis, consider which footbed firmness matches your tolerance.

If you have flat feet, you may need a more supportive footbed. If you have high arches, you might prefer a footbed that does not push too hard into your arch. Read our guide on how to choose shoes for high arches and how to choose shoes for flat feet for specific advice.

Both brands offer sandals with more than one strap configuration. The toe post style, which has a thong between the first and second toes, provides a different feel than a multi-strap design. Try both to see which holds your foot more securely. The sandal fit checks guide explains how to evaluate strap placement and heel hold.

Materials and construction differences

Birkenstock footbeds are made of cork, which is a sustainable material harvested from cork oak trees. The cork is blended with latex to create a flexible but firm base. The footbed is covered with a thin layer of suede, which absorbs moisture and provides grip. Cork footbeds can soften and mold over time, but they also require care to avoid cracking. If you want to know how to maintain them, see how to seal cork footbeds.

Taos footbeds are made of polyurethane or EVA foam, which are synthetic materials. They are lighter than cork and do not require the same break-in. The foam compresses slightly with use but does not mold as precisely as cork. Taos sandals often have a rubber outsole that provides good traction, while Birkenstock uses a rubber-like EVA outsole.

Both brands use leather straps on many styles, but some styles are vegan. If you prefer a plant-based or vegan sandal, check the upper material before buying. Read our guide on leather vs suede vs synthetic for more on material properties.

How to choose between Birkenstock and Taos

The right choice depends on your foot and your preferences. Try both on if you can, or order from a store with a good return policy. Walk around on carpet to feel how the arch support hits your foot. If you feel pressure on your arch, that might not be the right fit.

For a firm, stable footbed that becomes custom over time, choose Birkenstock. For a soft, cushioned footbed that feels good immediately, choose Taos. Consider your daily activities: if you stand for long hours, you might want more cushioning. If you walk on uneven terrain, a firmer footbed might be more stable.

What to pick for your use

Questions

Do Taos sandals have good arch support?

Yes, Taos sandals have a contoured footbed with built-in arch support and a heel cup. The support is firm but cushioned, making it comfortable for most foot types. It is not as rigid as Birkenstock's cork footbed, but it provides noticeable arch support.

What is the break-in period for Birkenstock vs Taos?

Birkenstock sandals typically require a break-in period, which can last from a few days to a few weeks, during which the cork footbed softens and molds to your foot. Taos sandals generally do not require a break-in period; they are comfortable immediately due to the softer foam footbed.

Which is better for plantar fasciitis: Birkenstock or Taos?

Both can help with plantar fasciitis because they provide arch support. Birkenstock offers a firmer, more rigid support that some people find effective for controlling overpronation. Taos offers a softer support that may be more comfortable if you have sensitive feet. Try both to see which feels better.

How does the width fit compare?

Birkenstock sandals come in narrow and regular widths, while Taos typically offers a medium width. If you have wide feet, Birkenstock's regular width runs wide, but Taos may be too narrow. Measure your foot width and compare with the brand's size chart to choose the best fit.
