I Want to Skip Outside but the CSX Pro Speed Jump Ropes / Skipping Ropes are for Indoor Use?

Yes the trade off for using fast cable ropes is that you can't use them outside. The plastic coating on the cable is hard wearing, however if you use it on an abrasive surface such as concrete it will wear through the rope very rapidly.

We recommend that if you skip outside use an interlocking gym mat (2 or 4 pieces stuck together depending on how much you move while skipping), this will also provide some cushioning for your knees. Or the other alternative is to add Duct tape to the middle of the rope + just keep replacing the tape when it wears out.
