what shop? most likely, your DIN should be set at 6 according to a DIN chart, but if they didnt adjust the wings, then yeah, thats their bad. for example, i am 6 feet, 160lbs, 315mm bootsole, and type 3+ skier, and my DIN according to the chart is 8.5. if you are shorter than me, lighter than me, or have a different size boot than me, you could end up at a 6. it also depends on if the bindings and boots were brand new or not. if you are pretty sure they werent set up right, take them back to the shop and tell them so.
