I'm a soon-to-be graduate who just invested in his first nice pair of shoes, a pair of Grenson's Sharp Boots; tan leather brogue boots with the double leather sole. http://www.grenson.co.uk/shop/sharp-189 I love the boots. I've yet to buy a shoe tree for them because I decided to wear them in a bit so I don't look like I care about my boots as much as I do. The problem is the sole. I've noticed that on the heel and on the tip of the toe, the sole has ground down to the point where there is starting to be a bit of wood damage, and somehow there is a central crack in the sole of the right shoe. I only noticed it yesterday. I am a bit amazed by this. I'd heard Grensons had a reputation for being hard-wearing by the standards of more expensive boots, but I've had these for less than two months. I don't think this should be happening. I've been wearing them a lot, most days when it doesn't look like it will rain, but after two months I'm still amazed by the hole. I feel almost cheated. Should I just replace the leather with vibram? How much would that cost? I'm particularly annoyed because I was really starting to enjoy leather soles-the sound they make is amazing, and after a bit of scruffing they're really very comfortable.
