Several weeks ago I was trotting around in 2-point when I felt a release of pressure at my right heel. I looked down, and sure enough, the zipper had separated in the heel area. I tried to unzip and rezip it to realign the the “teeth”, but it was jacked up and did not want to go. I asked around my barn, and was sent to a place down the road. This shop said that the zipper didn’t need to be replaced, and they realigned it super fast and super cheap- $13. I was very pleased, and felt like that would be the end of my zipper problems for awhile.
