Going Barefoot…almost! My barefoot experience and is it right for you? Part II

The pace number came from the op. Without a reference point for what that means, I don't know if that is his normal pace or that is slower than normal. My comment was that I, with a capital I(my quirky way of expressing that it applies to me only and not in general), felt the need to slow down. How much upper case I needed to slow down is not arbitrary but actual from experience.
Notice I also said from what worked from him...meaning you. Arbitrary meant that it is applicable to you but not necessarily someone else. I agree to slow down in the beginning. The amount is what I think is more individual. In any case, no worries because we both agree to slow down at first.
