ERGOfoot orthotic sandals are designed with a very supportive and comfortable footbed, and are usually recommended for feet ailments such as plantar fasciitis (arch/heel pain). The good thing about sandals made with orthotic arch support is that they help improve your gait, and also align your feet in the right position to ensure that the ankle is always in its correct position. When you wear sandals that are not made with orthotic arch support, the feet are too parallel to the ground and this stresses the ankle, knees and back. It is not advisable to use those kinds of flat sandals for long periods of time. Feel the difference and comfort of the Orthotic Sandals we carry.
