'Light track shoe, very commfy indeed, im on my second pair now and i love them!'
Strengths: very light! around 95grams so when you race you feel like you're flying! very comfy so no unwanted blisters or friction burns. For how good it is it is well priced. the colours are very cool too :)
Weaknesses: Not much to say for cons, only there is a tendancy for a hole to appear on one side (a small one) on one side of the shie where to fabric is not very strong (about 1-2cm), but it doesn't effect your running in anyway
Overall: Its Nikes best spike so far and there is nothing on the market like it!
