Weaknesses: Tread has worn quite significantly when compared to previous shoes for same distance (and I'm now a little lighter!) Pretty pricey with that in mind
Overall: All in all, a comfortable shoe. Loads of cushioning, I normally change my shoes around the 400 - 500k mark anyway but the tread at 400k has practically worn away around the ball region of the foot. First stability shoe, paid £90 for them, but I wouldn't say they were worth it.
Strengths: Far more accurate in my view than the Polar 400SD - I was never convinced with the accuracy of the Polar so I switched. Personally I find the GPS accuracy to be really good. Battery life and memory brilliant
Weaknesses: Size, shape and looks Software is not as good as the Polar, really only good for backing up your data, quite poor on the analysis. Can be slow for GPS to get a fix.
Overall: You wouldn't purchase this as a fashion accessory but it is functionally excellent. Using this instead of the Polar means I have far greater confidence in the instantaneous data and therefore I can push myself further. The screens are nicely configurable, you can view up to four fields on a single screen.
