If the shoe fits right, you shouldn't get blisters.
When being fittted for a shoe, the main initial consideration is a shoe with the correct level of support.
In theory, all the major makes (Adidas, Asics, Brooks, Mizuno, New Balance, Nike, Saucony etc.) will have a shoe that fits that support level.
In an ideal world, you would then try all those 7 shoes and go for the model with the best fit - I think that's achieved by choosing the shoe that "feels" the lightest and is the least noticable on your foot - that's hopefully because it fits the best and is "working with your foot". (sorry if that sounds a bit corny)
Unfortunately, each of those 7 will have different cushioning systems (gel, air etc) which feel different (softer/firmer etc), one of which the wearer might prefer or dislike.
Unfortunately, this often takes preference over the 'fit'.
That's when you get blisters...
