Does anyone have a pair of these? I have played Puma shoes for awhile now and haven't seen the Smart Quills except in catalogs, online,etc.
Can the Quills be replaced like a regular spike? Puma used to have Champ spikes before the S.Q came out....Do they feel different? Better or worse?

Thanks!

i've had mine for over a month with 6 plus rounds with them, so far so good. Really impressed how well the quills hold up.
