I can only tell you that Shimano shoes have nice wide soles which are good for drilling and attaching speedplay bases to. That's what I've been getting Scherrit to do for the last 10 years. I've also now got a pair of Giro laceups. I've not seen a list of shoes with 'further back' mounts. I've been asking around and looking for the same before but now I just stick with Shimano, Giro and flats on the MTB
