I like AGL (from
Nordstrom) the best for ballet flats, they have some nice low pumps too. Very soft leather, I have never had an uncomfortable pair and I have different styles and both rubber and leather sole types. The rubber sole type is a cheaper version usually made for
anniversary sale, but I slightly prefer this type actually as it doesn't wear down as much and you can wear it in wet weather. You can get the leather type re-soled though if it wears down, I just wear mine as is though as it doesn't really bother me.
I have 1 pair of Lanvins, beautiful shoes but not near as comfortable as AGL. I have 1 Tory Burch as well, it's actually a low wedge ballet pump, it's better than her flats but still not as comfortable as AGL. I have a few of the cole haan low wedge ballet pumps as well and they are comfortable but still AGL is the best. It's their soft leather that sets them apart from the others I think.
