No, this scout is the only one who is having an issue. I have also noticed that when he walks (we had an event today) he doesn''t walk so much as he "shuffles." As much as I hate to say it, (I really do!) but it is almost like he is too lazy to pick his feet up! We are going to monitor him closely on our next campout, which will include an introductory hike and see what happens. This will be his first with a pack. If it is an issue then we will speak with the scout and his mother about some alternatives.
