This is a set of five insoles that came with Mizuno safety shoes. All are unused. Based on the markings on the insoles, three pairs are size 26.0 cm, and two pairs are from 26.5 cm shoes. Measurements confirm they are nearly the same length. I removed these insoles immediately upon purchasing the safety shoes, as I use different insoles. They range from about 4-5 years old to more recent. Although difficult to see in the photos, three pairs have some discoloration on the back from storage, but they don't feel severely deteriorated. Please refer to photo 14. Some have more significant yellowing. Photo 15. One insole has what appears to be a crack in the heel area, but it doesn't seem to affect usability. Photo 10. Some insoles have original dirt marks on the back. No claims and no returns accepted. Please refrain from purchasing if you are seeking a perfect product or are overly concerned with minor imperfections.
