Flex groove sole assembly with biasing structure

摘要

An article of footwear includes an upper and a sole assembly. The sole assembly includes a groove that separates the sole assembly into first and second portions. Moreover, the article of footwear includes a flexible cord including a first end, a second end, and a middle portion. The middle portion extends through the sole assembly and across the groove between the first portion and the second portion. The article of footwear also includes an adjustment device that is operably coupled to the first end and the second end. The adjustment device is configured to move at least one of the first end and the second end to selectively adjust tension of the flexible cord between a first tension level and a second tension level. The first portion is more rotatable about the groove relative to the second portion at the first tension level as compared to the second tension level.
