Hi! I am deciding whether to purchase these boots from my friend. However, the condition of the soles really worries me. Here is a picture of them: http://www.facebook.com/album.php?aid=174851&id=670390888&upload=1 I am worried that since there are almost no fresh new holes in the ball of foot area I might have to use a plugged hole? Is that a good idea? I am putting figure skate blades in heh place of these synchro blades. Will I have a problem with the blades if all the ball of foot area holes are either presently screwed and there is only one fresh area for holes on the heel of both boots? Thanks so much!
