Standard airline grooming regulations generally require female cabin crew to wear heels with a height ranging from 1.5 inches to 3 inches (4cm to 7.5cm) while in public areas or during boarding. These are often referred to as "terminal shoes" or "ramp shoes." The requirement is intended to maintain a professional, sophisticated appearance that aligns with the airline's brand image. However, most airlines allow (and encourage) crew members to switch into "cabin shoes" once the aircraft is at cruising altitude and service begins. Cabin shoes are typically flats or very low-profile heels (usually under 1 inch) that provide better stability and comfort for the physical demands of working in a moving galley and walking the aisles. For male cabin crew, the standard is a polished, flat dress shoe. In recent years, some progressive airlines like Akasa Air or SkyUp have moved away from high-heel requirements entirely, allowing sneakers or ergonomic flats as part of the primary uniform to prioritize employee health and safety, particularly for emergency evacuations where heels can be a hindrance.
