This morning's swim was OK, I worked on "stroke-stroke-stretch" to try to reduce my leading arm dropping during breathing. This is when I tend to lose the front-quadrant style the most. I also did some arm and leg drills including trying to use my arms at a slightly higher rate.
After coffee we drove to Attercliffe and I tried on Ultra 290s in both size 9 and 9.5. After much to-and-fro I settled on the larger 9.5 pair and hope it won't be too loose. The chap in the shop recommended butterfly lacing to improve the heel fit which seemed to work. It was a new idea to me but appears to be well known online.
