I bought a set of these last spring at the end of ice season on sale, so I had to wait until this year to try them out. First - the Large size fit my Baffin Titan size 9 boots like they were made for them. Perfect tension and placement of the diamond chains on the bottom of the soles. I used them the past two weekends out ice fishing. The second weekend was glare smooth ice that re-froze after it rained and it was like walking on pavement - great traction and secure footing. I felt very secure. They are also not very intrusive on regular floors dont tear up surfaces that you have to walk on especially indoors. In fact other than the improved Ice traction I could say that I almost didnt notice them there. Excellent for my use Ice Fishing.
