I've had mine about 10 years; my sister has a pair that are 20yrs old, been re-soled twice. they are really great shoes, well worth the price. I love my Birks but there is no way I could wear them for a whole week. Mine are the two-strap kind, with no heel strap. If I wear them long the top of my foot gets sore, then my shins start to hurt. My feet are terribly flat and even though Birks have tremendous arch support, they aren't enough.
