Took the plunge and bought a pair of flows - felt much nicer than connects when I tried them in the shop.
First run today - total heaven for first 5k, but even though I have been a midfoot striker for some time, they really bring the landing point even forward - result is you feel you're floating, but the calfs were killing me in the soceond half of my 6M run.
I should have listened to good advice and started with a shorter run as they clearly need adaptation period, but otherwise am really excited about them.
Comfortable like old slippers, no rubbing issues at all.
