Finally I was able to do my first 30 minutes in them today. I already got them on the 30th, but did not have time to wear them.
I honestly like the lower to the ground feeling and the toe area was fine, it was actually softer than I thought. The clear sole was a bit slippery, but that was due to the court I believe, was not the cleanest.
The top laceholes, the round ones with the I guess plastic frame, were pinching a bit into my ankle, so I will monitor that. I tightened the laces and then it was not noticeable that much. I will give them a thorough wear the next two weeks, probably three times both weeks and 1.5 - 2 hours per session and then I will post my impressions in the thread.
