Step 2: The Why, and the only step
The only step? Remove the insole. However, depending on the brand of aquasocks, there might be some adhesive to deal with, or, as with the Target pair, some venting holes that might be uncomfortable. You get used to it. If you leave in the insoles, there really ins't much support, so you would still get most of the benefits. I have already worn through one pair, but at $10 per pair, it won't break the bank. This is a GREAT way to try out the techniques without spending lots of money.
