I purchased the GRIP-INATOR II not for ice sport, but for painting a standing seam metal roof. I was feeling insecure in my work shoes, these are definitely grippy, and surprisingly comfy. Its like walking on carpet!! I was concerned about size as I am an 8.5 I ordered size 8 and they fit perfect, even with orthotic inners added. I am finding little bits of the sole are slowly breaking off, that is not unexpected as I am not using them for the intended purpose. I doubt they will last a long time on a roof at is a touch environment, hot and steep, but that is OK as I feel very secure in them. Definitely recommend.
