Questions about Deuter Kid Comfort I Set

No, unfortunately not.

There is a seat, but no footrest. The little one will be able to swing them happily during the ride.

There may be more differences, but what I see is there are no hip pockets and foot straps on this model.

None of them. It's not on the Deuter website either. Allegedly, Deuter accessories don't fit either. Nevertheless, a super carrier, very comfortable, and for the price nothing to complain about.
