As you know, different Graf skate models have a wide variety of fits. The Graf G75 has a bit more of a pronounced heel fit than the Graf G7s. The heel instep depth on the G7s are a tad deeper than the G75s. I have attached a great link provided by Graf describing all of the models that Graf offer including the two models you had questions on.
