I have this one. It certainly works fine. And the block is soft so it's not hurting or anything.
Anyways, it's abit hard on your feet if you plan to walk long (1 hour +). It's not hurting at all, but you'll feel a lil numb. But anyways, it's worth if you want to buy it ^^ I'm still using it almost everyday ^^
btw, i can't see the 1st link so i can't comment anything on that
