Can you tell when the puppy arrived? Am I headed for TMTS (Too Much, Too Soon)? I'm doing 2/3 of this in my marshmallow sandals, I can feel my heels regressing a bit, getting sore and not allowing a proper walking gait in minimal shoes. I'm back to a forefoot strike in the mocs to compensate. My knees bother me while I'm wearing the sandals, but I seem OK afterwards. I'm doing a half mile a day in my moccasins and still feeling strong doing that.
