I've tried 3 brands and here are the measurements:Thinnest is Pedifix 1/8" thick, 2 1/2" wide, 2 7/8" long (that's 3mmX6.3cmX7.2cm).Medium is Happy Feet 3/16" thick, 2 3/4" wide, 3 1/4" long (that's 5mmX6.9cmX8.7cm). My favorite with a bump in the center.Thickest is Metatarsal Pads by Native Edge 5/16" thick, 1 3/4" wide, 2 1/2" long (that's 8mmX4.5cmX6.5cm). Felt covered is slightly thicker.PediFix are good added to some insoles that already have a slight metatarsal bump built in.Metatarsal Pads from Native Edge are good quality and a good value with several pair in the set, but too thick for me. Neither heating and flattening nor cutting off a slice worked.
