Maybe. I had Alphfly 1s and only really raced up to HM in them and had horrible arch blisters. Ended up ripping out the glued-in insoles and putting one in from another shoe which fixed the issue at the cost of a tight fit. Took them on a few solo big runs until the silly air things popped in one foot on a 50k and left me with hip pain for a month.
They are incredible for locking onto a given pace and just staying there.

Have moved on to Metaspeeds. No problems.
