It has low Q factor i.e., it is closer to the cranks than most pedals. It helps increase efficiency but some people prefer to have the pedals farther away from the crankset.
So, while sitting on your bike, move your foot closer to the crank arm and see if you'll be comfortable with that position and if so, you'll have no problem with the Ergon pedals.
I have tried them at REI, very comfortable, the only reason I didn't get them I already have a good set of flats.
Also the sale is only for small sized pedals. My shoe size is 12 and I prefer large.
