I am having a problem with my RLPL Mackays that I hope someone can shed some light on. The left shoe does not seem to be breaking in properly. When my foot bends during my normal walking stride, the shoe puts pressure on the base of my big toe, creating/aggravating a blister. I suppose I am partially to blame for not wearing the shoes 2-3 hours at a time to start, but this has not happened with my right shoe, nor has it happened with any other pair of shoes I own. Has anyone else experienced a problem like this? Will it resolve itself over time?
