PigaONE is available in 5 sizes ranging from women’s 5 – 11.5 and men’s 7 – 12.5 (US sizes).
We recommend to go a size up if you have wide feet, and to go size down if you have narrow feet. Here are 2 examples:
1) Mary wears a size US 6 and has wide feet, so she chooses size US 7 (M – Medium)
2) Bob wears a size US 12 and has narrow feet, so he chooses size US 11 (XXL – XXLarge)
