I have the three-strap Sidi MTB shoes (can't recall model name, Bullet perhaps, but they have 3 velcro straps without the buckle deal that the super high end ones have) and I love them like I love their road counterpart. I've also had the 2-strap Sidi MTB shoes (again, memory fails me regarding model name) but for some reason Sidi saw fit to route the upper strap so the tag end is on the crank side thus occasionally unfastening the velcro at the most inopportune times...stay away from that one. Since you know Sidis fit you & you like them then you may as well stay with Sidi, eh?
