Does anyone know if last year's Nike Zoom Waffle XC Spikes were better than the model from 2 years ago? The 2 year old model had 4 individual floating spike holes, which after worn once got all bent and made it almost impossible to change the spikes. It looks like last year's model has an actual spike plate with holes for 6 spikes instead of 4. The reason I ask is that they are on clearance for $29 and I am thinking about picking up a pair. Any info would be great!
