Very disappointing quality considering this is an expensive premium shoe for Adidas. Under 50K running usage and then a suspected energyrod or something snapped (couldn’t see the cause of the problem on the sole) in the left shoe as it then made a clicking sound with each step. Sent back to Adidas for quality issue after such little usage but they just said they didn’t meet the return conditions (??) & returned the shoes back to me. No issues with other Adidas running shoes so perhaps an isolated issue but will now try Asiscs Megablast.
