Very disappointing.  These are definitely not the same Rod Laver shoes from even 10 years ago, not close to the originals.  As other reviewers have stated, the soles are very heavy.  The soles feel as if Adidas used concrete instead of rubber.  I've worn men's size 10 in all shoes for 25 years and these in a size 10 are too long.  Extremely uncomfortable and wouldn't want to wear them running or any sport type activity.
