Little to no cushions in trainers can cause issues, but can too much cushion/support like in the Asics Kayano shoe cause issues??
For runners who need a control shoe (ex. overpronators) over cushioned shoes can cause injuries. It’s not that cushioning is bad, its the amount of mobility that the cushioning allows. A soft shoe allows too much knee roll for overpronators and that’s what causes the knee problems.
