Even with $6.95, shipping, that matches the lowest total price we've seen for any pair of Skechers Tone Ups, which has not resurfaced since June of last year. These sandals boast the ability to burn more calories and tone and strengthens your backside and legs better than walking in regular shoes. This won't last, so act fast. There is no sales tax (except KY, NC, NV, NY).
