Timberland PRO replacement footbeds offer the same all-day comfort as our original boot footbeds - and more. The anti-fatigue technology footbeds feature our unique inverted cone design for shock absorption and energy return, while our new footbed powered by Insite incorporates fcx technology for additional arch support to help prevent injuries and fatigue. They are moisture wicking and highly resilient with dynamic arch support to keep feet feeling energized throughout the workday.
