Is it permissible to step on a spot where water has been poured to purify it from urine while it is still wet, and is the wetness resulting from walking on it considered pure?

An impure spot is purified by removing the substance of the impurity, then by drenching it with abundant water until it covers the impurity, such that no trace of the impurity remains, neither in color nor odor. If the place has been purified, then anything that touches it, such as a garment, foot, or the like, does not become impure, even if the place is still wet from the purifying water.
