I recently bought a pair of Cavallo Piaffe dress boots, and they fit perfectly. However, when I get on my horse, there is a gap at the very top (the Spanish top portion) about a centimeter away from my leg. I can easily get them taken in or have a zipper inserted, however I'm not sure if this would be effective because the Spanish top is only on the outside and does not wrap around the whole leg. Has anyone else had this problem? Will the boots break down enough for the top to hit my leg in a better place?
