Bought new insoles because original ones that came with my sneakers (NB Arishi v3) got worn out. (There's a hole in it) I like the cushioning that the new insoles provide but because they're a bit thick, like 5mm all around, they make standing in these shoes feel unstable, like i feel my feet are going to roll outwards, esp when standing on inlined surfaces. Is this normal? These memory foam arch support insoles are sold everywhere so i find it hard to believe that they have such a major flaw.
