I have many pairs of Tod's classic drivers, as well as some from other brands, and I have gotten A LOT of wear out of most of them. I have never had the issue of the pebbles wearing down tremendously, they will soften and wear down a bit when being broken in, but after that they are fine. That being said, they are not really designed to be worn for city pavement-pounding, and are not really that comfortable for longer walks (absolutely no support). You also have to be careful not to walk on gravel, chunky dirt, or anything sticky, because it could easily ruin some of the pebbles. I was once in my shoe repair place on 55th street, and a woman was having her gommini soles replaced with an ultra thin rubber sole. It didn't look bad, and the pebbles remain on the back part of the shoe, so it still had the classic Tod's look. These shoes are extremely versatile, and the quality is quite good, but if you want something a little more carefree I suggest going with something by Prada or LV (the Lombok's are great and have a rubber-strip sole instead of dots).
