The New Balance MR1123 is a running shoe that is designed to provide a high level of motion control and stability for runners with a lower arch. The shoe is a replacement for the MR1122, featuring a synthetic/mesh upper and has an N-Lock support system which pulls the shoe around the foot for better support. The outsole of the shoe is made of N-Durance rubber compound for strength and durability and it has a blown rubber forefoot which is light and flexible. It also offers ROLLBAR technology with medial and lateral TPU posts for enhanced motion control. The entire midsole of the MR1123 is made of Abzorb FL cushioning and it includes Abzorb SBS cushioning in the forefoot and heel for enhanced shock absorption. It also has a moisture-wicking collar, suede overlays, and reflective detailing for safety while running at night. The MR1123 comes in a white/navy color and is also available in a women's model, the WR1123.
