Very nice insoles. I have two pairs of Birkys and these make all of my shoes feel like my sandals.<br /><br />Update. I found after wearing these insoles for a few days that in my dress shoes (Ecco and Clarks) that they fill the shoe quite full. Not super tight but somewhat comfortable. I like the feel of the arch but they do lack a little in length. I wear a size 43 in birkenstock shoes and I bougth these in a 43 but without an end to them my toes hang a little off the end of them in a normal shoe. I would recommend if you wear brinkstock shoes in a 43 to get a size 44 in the insoles. I will say that by far I am most happy with the sof sole insoles the best. I have tired these, superfeet and sof soles and like sof soles the best for me.
