Yes, it really depends on the shape of your foot. Angie has overall narrow feet with a regular instep (I think). And she is a whiz with insoles!
But if you have feet that are wide or normal width/ volume at the front with a higher instep, plus a narrow heel, it's just going to be a trickier fit in most cases, though every now and then you will get one that works. The risk with an insole to fill the shoe (for this type of foot) is that it simply lifts the foot too high up and if the shoe has lower sides, the heel will end up even looser -- I've found that need that extra depth at the front of my foot.
I remember going to Nordstrom's in Michigan with former fabber Svetlana. She could not believe her eyes -- I must have tried on 20 pairs of pumps/ loafers and walked right out of them every time.
I never cease to wonder at this. My dad wore loafers every day.
How did he do it?
Mr. Suz has narrow feet with a high instep and he somehow wears loafers, but only from a very specific company.
Donna, what is a tongue pad? This is also interesting me....
