Does anyone have before and after pics that they could share of the soles that were vibramed? I am in love with these flats (feel like butter), but I want to make sure that the shoes will be worth it. Do you suggest getting the soles vibramed before even wearing them for the first time? I loved these shoes when I tried them on, but just worried about how they wear. I tried on Lanvin and Chanel flats and they both hurt my heel. This is the first flat I've tried on in years that does not hurt my heel.
