A flexible shoe assembly for use in a molding system. The clamp unit of a molding system includes a moving platen and a stationary platen supported by a frame. Tie bars interconnect the moving platen with the stationary platen. The tie bars are secured to the stationary platen and pass through respective openings in the moving platen. Each tie bar is supported and guided within their respective openings by a flexible shoe assembly and wear pad. The flexible shoe assembly has a force redirector for directing force away from a peripheral edge of the wear pad towards a central force area. The flexible shoe assembly also includes a load distributor to distribute the load across the wear pad surface. The flexible shoe assembly includes an upper support that is flexible about a lower support to keep the wear pad in operational contact with the tie bar.
