A furniture glide is mountable on the foot of a furniture leg. The glide is constructed around a glide base having an inner portion and foot support surface. A plurality of spring fingers positioned on the glide base have attached and distal ends. The distal ends extend in an inward direction toward the inner portion of the glide base. The distal ends also extend in an outward direction away from the foot support surface. The positioning of heads at about the distal end of each spring finger allows the spring fingers to receive an outward expansion force when the foot is moved toward the foot support surface. The spring fingers are positioned to move in an inward direction toward the inner portion of the glide base to lock the foot to the furniture glide when the foot contacts the foot support surface.
