Invoke 2 Walking Shoe

I have worn Ryka sneakers for a long long time. I usually have no complaints. I bought 3 pairs of sneakers recently and the complaint I have is about the insert. It used to be so much better with nothing to complain about but these last 3 pairs are not up to par...like my other ones. No cushion and they move.and I feel the new sneakers are also not the same. They feel different and not as comfortable as my older ones. I know there is a break-in period. But I never had to have a break-in period before. They even feel a bit smaller than they used too!!
