Here's an edited video with Amy Stran showing off two types of Spenco sandals. She's in the thong version most of the time but also shows off the slide version at the end of the video. She's helped out by two great QVC models, Sheila Alasha (Brunette) and Ellen McMonagle (redhead).
BTW, Amy is barefoot in the video at times, but there are no closeups.
