The "Lifetime Warranty" means that the shoes are protected from any manufacture defects. This does not mean that you just get to trade them in when they wear out. Shoes are usually stitched or glued together in some way and will, from time to time, fall apart due to a mistake or improper production, like the brakes on your Prius. If this is the case, Etnies will replace them with the same, or similar shoe. You do not get a new shoe cause you skate in them and wear a hole in them, or they wear down just from wearing them.
