I tried the Giro ProLight SLX shoes and I like them a lot - simple, with no buckle or wire and feather lightweight, well ventilated and comfortable and stiff. Almost perfect. But one of the biggest cons with the SLX is the super thin, non-replaceable heel pads.

What other top of the line SPD-SL shoes are there that are
- similarly lightweight and simple (the less buckles or wires, the better, i hate finicky "features", I prefer velcro and definitely not considering laces)
- and compatible with SpeedPlay
- and have replaceable heel pad
