Strengths: I bought them from a Nike outlet for £50. I found as stated the laces took some getting used to and it caused me some foot problems. Once sorted no issues, though I wear insoles so strugged a bit getting it right. Quickly settled into them
Weaknesses: As with previous tester after doing about 100 miles they got a small hole in them which rendered them useless.
Overall: Not reliable enough to justify the cost even from an oulet mall. Would not buy again
