The present invention concerns a shoe (10) including an upper (12), having lateral and medial sides, a midsole (14) joined to the upper (12), and an outsole (16) joined to the midsole (4). Shoe (10) is tightened around the wearer's foot using a lacing system (18) comprising a lace (20) and tightening mechanism (22). Lace (20) is threaded through shank (24) positioned under the arch and heel wrap (26) and attached at opposite ends to tightening mechanism (22). In an advantageous aspect of the present invention, lace (18) is tensioned to draw shank (24) upwards and towards the arch of the foot.
