Lunch- 8+2. Felt good. Foot didn't hurt, and I didn't feel sluggish after a few days off.
In case you're wondering, that really is 19 pairs of shoes listed above. And I have 2 more still in the box. That's a whole lot of rubber and cloth sitting around my house. Assuming each shoe lasts 500 miles, I've got 5500 miles left- almost 2 years.
