I purchased this item new and have stored it at home for a long time. I don't think I've used it more than 5 times, but the four attachment points for securing the inner shoes to the outer shoes are missing (circled in red in the last photo). In addition, please understand that there may be deterioration due to the passage of time. These are diving boots with a mesh slip-on style and non-slip soles. - Size: EU 42 M - Material: Mesh - Design: Slip-on style - Features: Non-slip sole - Uses: Diving, Snorkeling Thank you for looking.
