I had the same, progressively worse to eventually impeding walking. I went and saw a physio. He gave me stretches that helped. Most importantly he explained the whole friction thing. I loved my "old" Time shoes so much I just kept using them even though they were falling apart. The padding at the back of the shoe was starting to tear and deform - he explained this could have been the start of it, increased friction. Check your riding shoes. Second, he looked at the casual shoes I was wearing, same problem - I seem to wear this section of all my shoes out rather quickly. Finally, I also swam at various times in the year and used flippers for different workouts - this may also have been contributing. In my case, retiring the old Times for new ones made the biggest difference, but I now pay attention to all the shoes I wear in terms of potential friction points.
