When a shoe is pinching, you don't have to limp around in pain searching for a suitable pair before you take off the bad shoe, you simply take off the offending shoe first to get some relief.
In our case, we are lucky we already have a second pair, how will we know it fits if some are telling us its worse than the pinching shoe even before we or they try it.
