Converse Jack Purcell Signature Leather Ox in White. The classic Converse Jack Purcell silhouette is crafted from a soft-brushed Nubuck upper. The leather upper holds both comfort and durability, with an OrthoLite foot bed and Nike Zoom Air elements. The outsole of the silhouette shows blue line detail to the toe and Converse branding to the heel. Jack Purcell lettering is also engraved into the leather tongue for a signature finish.
