a sock (11) disposed within the boot (101): and a bladder (19) disposed within or on the sock (11), wherein the bladder (19) is configured to undergo repeated inflation and deflation so as to stimulate blood flow in a wearer of the blood flow stimulating device, wherein the sock (11) further includes a toe region (1002), a heel region (1001) and a raised portion (1003) between the toe region (1002) and the heel region that (1001), in use, reduces the distance between the sock (11) and a foot of a wearer of the blood flow stimulating device at the raised portion of the sock. ## Claims ### Claim 1 An offloading support device, comprising: a shin support structure; an offloading element connected to the shin support structure, wherein the offloading element has a stem portion twisted towards a front of a tibia of a wearer, and a plate portion connected to a bottom of the twisted stem portion; and a module positioned within the shin support structure, the module including a fluid reservoir connected to a bladder. ### Claim 2 (depends on 1) The offloading support device of claim 1, wherein the plate portion comprises at least a hole configured to couple to a sole of a boot. ### Claim 3 (depends on 1) The offloading support device of claim 1, wherein the twisted stem portion further comprises a padded fabric sleeve disposed around an outside of the twisted stem portion. ### Claim 4 (depends on 1) The offloading support device of claim 1 wherein the offloading element is connected to the shin support through a slide fixing located on an outside of the shin support, the slide fixing having at least a screw adjustable to different positions relative to the offloading element. ### Claim 5 (depends on 1) The offloading support device of claim 1, further comprising a sock connected to the plate portion, wherein the bladder is disposed in the sock and configured to expand. ### Claim 6 (depends on 1) The offloading support device of claim 1, further comprising a conduit connecting the bladder to the fluid reservoir wherein the conduit aligns with the twisted stem portion of the offloading element. ### Claim 7 (depends on 1) The offloading support device of claim 1, wherein the module further comprising: an air inlet; a first valve connected to the fluid reservoir; a second valve connected to the fluid reservoir; an electric pump in communication with the air inlet, the fluid reservoir, the first valve, and the second valve; and a controller, connected to the electric pump, wherein the controller is configured to pressurize the fluid reservoir through the electric pump. ### Claim 8 (depends on 7) The offloading support device of claim 7, further comprising a solenoid valve connected to the fluid reservoir and a bleed valve, wherein the solenoid valve is configured to switch between a connection of the bladder to the fluid reservoir to a connection of the bladder to the bleed valve. ### Claim 9 (depends on 1) The offloading support device of claim 1, further comprising: a proximity sensor; and a memory for storing data; wherein the proximity sensor detects whether the wearer is wearing the support device and data produced by the proximity sensor is stored on the memory. ### Claim 10 (depends on 1) The offloading support device of claim 1, further comprising a temperature sensor disposed within a sole of a boot connected to the twisted stem portion of the offloading element and configured to indicate a rise in temperature being indicative of skin breakdown on a foot of the wearer of the support device. ### Claim 11 A support system, comprising: a shin support structure; a boot having a sole and an upper; and an offloading element connected to the shin support structure and the boot, the offloading element comprising: a stem portion twisted towards a front of a tibia of a wearer; and a plate portion connected to a bottom of the twisted stem portion; and a module positioned within the shin support structure, the module including a fluid reservoir connected to a bladder. ### Claim 12 (depends on 11) The support system of claim 11, wherein the plate portion comprises at least a hole configured to fasten to the sole of the boot. ### Claim 13 (depends on 11) The support system of claim 11, wherein the stem portion further comprises a padded sleeve disposed around an outside of the stem portion. ### Claim 14 (depends on 11) The support system of claim 11, wherein the bladder is disposed in the sole and is configured to expand. ### Claim 15 (depends on 11) The support system of claim 11, further comprising a conduit connecting the bladder to the shin support structure, wherein the conduit aligns with the twisted stem portion of the offloading element. ### Claim 16 (depends on 11) The support system of claim 11, wherein the module further comprising: an air inlet; a first valve; a second valve; an electric pump in communication with the air inlet, the fluid reservoir, the first valve, and the second valve; and a controller, connected to the electric pump, wherein the controller is configured to pressurize the fluid reservoir through the electric pump.
