I have tried many different types of Sock on the bottom of PJ's and I have bocked on a set of sevens in the rain
The 7 hoofs give very good wear and good grip in the dry and on rough surfaces in the wet but I felt that they slipped on wet pavements and wet smooth asphalt (wet cobbles were interesting to) only had them for a short time so maybe they grip better in the wet when they wear a bit
I have now returned to Hoofies rubber and I find it feels more secure in the wet on smooth surfaces
I know I sell them so I must be concidered Biast so this is a personal opinion but if your at a meet with me and it rains I'll let anyone try them and see if they agree
