Birkenstock Birko-Balance Unisex Orthopedic Insole Narrow Fit
Description
Birkenstock Birko-Balance Unisex Narrow Fit Orthopaedic Footbed: Birkenstock anatomical comfort in your everyday shoes
The Birkenstock Birko-Balance is the orthopaedic footbed that brings legendary Birkenstock anatomical comfort into your favourite closed-toe shoes, of any brand. Designed with the same anatomical structure as the original Birkenstock footbed, it supports the arch of the foot, stabilises the heel, and promotes a balanced distribution of body weight, reducing fatigue when walking. The cork and latex base progressively adapts to the foot's morphology, offering personalised and long-lasting comfort that improves day by day. The breathable microfibre upper lining ensures excellent moisture management, maintaining a healthy microclimate inside the shoe. In the narrow fit version, this accessory is ideal for shoes with a small internal volume and for those with slender feet.
Anatomical cork and latex structure: the secret to Birkenstock comfort
The structure of the Birko-Balance is inspired by the natural footprint left by the foot on sand. The deep heel cup stabilises the heel in its natural position. The longitudinal arch support supports the arch of the foot, relieving the plantar fascia. The transverse arch support stabilises the metatarsal bones for secure footing. The raised toe bar protects the toes when walking. The base made of 90% natural cork and latex is flexible, lightweight, heat-insulating, and has antibacterial properties.
Microfibre lining: breathable, hygienic, comfortable
The breathable microfibre upper lining quickly absorbs and releases moisture, keeping the foot dry and maintaining a healthy microclimate inside the shoe. The soft, skin-friendly surface provides an immediate feeling of comfort.
Narrow fit: for shoes with limited volume
The narrow fit version is designed for closed-toe shoes with a smaller internal volume and for slender feet, ensuring stability without constriction.
