I got these shoes because they had great reviews and I had not bought a pair of running shoes in 2 years.
I have already ran 4 miles in them and this is what I think:
they are the lightest most comfortable tennis shoe I have tried on ever
HOWEVER - they offer very very little ARCH support. I may put in an insole but they are not terrible without
They run very true to size in my opinion - I wear an 8.5 in heels and a 9 in flats. I bought a 9 in these and they fit perfect.
