Black running shoes from New Balance with GORE-TEX material for waterproof performance. I think they can also be used for business casual wear. Gore-tex model from the neutral cushioning model "Fresh Foam X 880 V14". The single-layer midsole provides smoother weight transfer and stable running during the run.

The balance of stability and cushioning supports a wide range of activities, from daily training to full marathons. 【Materials】 Upper material: Synthetic fiber Outsole material: Rubber sole Midsole material: Synthetic sole
