    • Foot support systems include a fluid flow control system that facilitates movement of fluid into, out of, and/or within a sole structure and/or article of footwear, e.g., to change and/or control pressure in fluid filled bladder(s). Such foot support systems (1000) may include a first foot support bladder (200A), a fluid tank (400), and a fluid distributor (720). The fluid distributor (720) may include a distributor body that has: (a) a first solenoid mount (710A), (b) a second solenoid mount (710B), (c) a main fluid distribution channel (714A, 4920) in fluid communication with the first solenoid mount (710A) and in fluid communication with the second solenoid mount (710B), (d) a tank channel (714B, 716B) in fluid communication with the first solenoid mount (710A), (e) a first foot support bladder channel (714C, 716C) in fluid communication with the second solenoid mount (710B), (f) a first foot support connector (730D) connecting the first foot support bladder (200A) with the first foot support bladder channel (714C, 716C), and (g) a tank connector (730C) connecting the fluid tank (400) with the tank channel (714B, 716B). A first solenoid (4900A) is engaged with the fluid distributor (720) at the first solenoid mount (710A), and a second solenoid (4900B) is engaged with the fluid distributor (720) at the second solenoid mount (710B). In some examples, the fluid distributor (720) further may include: (a) a fluid source connector (730B) that receives fluid from a fluid source (e.g., pump (500)) and supplies the fluid to the main fluid distribution channel (714A, 4920) and (b) a connector (730A) that receives fluid from the external environment and directs it to the pump (500). Additionally or alternatively, in some examples, the fluid distributor (720) may include a third solenoid mount (710C) and a second foot support connector (730E) that direct fluid to and receive fluid from a second foot support bladder (200B).
