New shoes
Fit well right out of the box. I have fit issues among several brands, but the online text help assured me that these were true to size (Addidas are inconsistent for me), and they were. Played in wet conditions and had no traction issues, although there was no mud. Suspect that the treads would be less stable in muddy ground than real spikes (soft), but I seldom try to play in those conditions, so it's probably a minor concern.
