"sensors in their high-end footwear ranges that measure wearers' activity and performance"
WHY? I can understand professional athletes having a use for that but for normal people what is the point?
I really wanted to find a use for this year's crop of new smart watches but couldn't find a useful feature among them. Heart rate, number of steps walked, wave your arm like a mad man to pay for things, etc... its all nonsense I do not need and would not use.
