The mineral clay version in Converse's Hi-Top Utility range. Has the round laces that lace up through an eyelet then the plastic hook that's on the outside. Comfortable, but slightly rigid given the plastic reinforcement. Had high hopes of fitting my feet into these, but just one size too small, so barely worn. Unisex: USM 6, USW 8, UK 6, EUR 39, CM 24.5
