Strengths: Plenty room. High milage shoe. feels like running on air.
Weaknesses: Maybe a bit on the heavy side but I did not notice.
Overall: Great for people with lower arches, Been a asics man up until longer distances in my 2080's started giving me instep Blisters. Shoe shop recomended these as asics are made for high arch feet!.
'VERY USEFUL WATCH TO HELP YOU TRACT YOUR PROGRESS.'
Strengths: User-friendly as long as you take time to read the manual. Top quality workmanship. Some say it a bit big but there is a lot packed into this baby.
Weaknesses: Price - but I guess you get what you pay for.
Overall: Very happy - had a problem with the foot pod after a few months but it was fixed and returned by Polar within a week as it was still under warranty.
