Too many to list. I keep a full time subscription to allyoucanfeet.com. Wu's feetlinks sites, I have at one time or several times subscribed to them. Feetoverforty.com was the best of all time, but no new content in years. Feetwonder.com is new, with great content but not many pics each month. I would love to find one I never subscribed to, but that might be a fleeting wish.What are the paid sites you use or have used?
