Stride Shift Sugar Free Gum is the gum you will never forget. You may not be ready for Stride Shift gum - it changes flavor mid-chew, like something out of movie about a poor boy who wins a chocolate factory in a contest. But Stride Shift is real and starts as a berry flavor and shifts to mint. Stride Shift Berry Mint is available in a 12 count box, with 14 sticks per pack.
