I actually bought these also! For me they were a nightmare, despite having good reviews. They feel comfortable etc when I put them on and walk around, but just found them so awkward for running in, though I couldn't decide why. Partially due to the heel-toe differential being larger than I'm used to with all my pairs of new balance road runners. Found it awkward to run any way other than heel striking.
I am a heel striker, particularly when fatigued or at slower paces and my normal lsr shoe is 12mm drop, so the 10mm of these is less. I feel I need more cushioning for the lsr and reckon these will fit that purpose. Tuesday at earliest before I receive them.
