Orthotics are specialized inserts placed inside footwear to manage biomechanical foot issues, provide targeted support, and redistribute pressure evenly across the foot. They improve overall foot function, alignment, and reduce strain on the body’s kinetic chain. Orthotics can be worn with sandals, but it requires selecting very specific shoe construction.
Why Traditional Sandals Do Not Work
Conventional sandals, such as basic flip-flops or fashion-focused strappy models, are generally incompatible with orthotic inserts because they lack the necessary structural elements. These sandals typically feature a flat footbed or one with a shallow, non-removable contour that conflicts with the custom shape of the orthotic. Attempting to place an orthotic on a molded footbed can create an unstable and uncomfortable fit.
Most fashion sandals also lack a deep enough heel counter or side walls to contain the orthotic device. Without this containment, the orthotic can slide excessively, defeating its purpose of providing consistent support and alignment. The minimal strapping found on many sandals provides insufficient coverage to secure both the foot and the inserted device, often leading to instability and the foot slipping out.
Sandal Features That Accommodate Orthotic Inserts
For those wishing to use their existing custom orthotic, the sandal must be explicitly labeled as “orthotic-friendly” and possess a removable footbed. This feature allows the wearer to remove the manufacturer’s insole and replace it directly with the custom device. A removable footbed is the single most important factor for accommodating a custom orthotic.
The sandal must also offer adequate depth, often referred to as an “extra-depth” design, to ensure the foot and orthotic sit securely within the shoe. Since the orthotic adds height, the sandal needs this extra volume to prevent the heel from popping out. The straps should be adjustable across both the forefoot and the ankle to allow for a customized fit. This adjustment is important for securing the foot and preventing it from shifting or sliding over the support structure.
Alternatives: Built-In Orthotic Footwear
A popular alternative to transferring an insert is wearing sandals that already incorporate orthopedic support directly into their design. These are often the most practical solution for casual summer wear because they eliminate the need to constantly swap inserts between shoes. Such footwear is engineered with a contoured footbed that mimics the biomechanical support of an orthotic.
These supportive sandals feature built-in attributes like a molded arch support and a deep heel cup that cradles the heel bone. The deep heel cup provides stability and helps control excessive inward or outward rolling of the foot (pronation or supination). The integrated arch support helps distribute weight evenly across the foot, reducing strain on the plantar fascia and offering relief for conditions like plantar fasciitis.
Many of these sandals also incorporate shock-absorbing materials, such as EVA foam or polyurethane, in the sole to cushion impact and reduce stress on the joints. This built-in support promotes better alignment throughout the entire lower body, which can improve posture and alleviate discomfort that extends to the knees, hips, and back. While these supportive sandals are often sold over-the-counter, they offer a high level of comfort and stability for those who need foot support.
