EE's design quickly developed into a fairly simple cylindrical fuselage with an ogive nose cone, four cropped-delta wings just behind the middle point of the fuselage, and four smaller control surfaces at the rear, in-line with the mid-mounted wings.
The fuselage had a slight boat-tail narrowing at the extreme rear under the control surfaces.
The sustainer was to be a liquid fuel rocket developed for the missile, and was launched by four large "Gosling" solid fuel rocket boosters lying between the control surfaces and wings.
The boosters featured a single oversized fin of their own, and are particularly easy to spot due to a small flat surface at the end of every fin.
This surface provided an outward drag component that help pull the booster away from the main body when released, helped by the booster's asymmetrical nose cone.
Guidance was via semi-active radar homing, the Ferranti Type 83 "Yellow River" pulsed radar serving both as an acquisition and illumination system.
The same radar was used with the competing Red Duster.

The test programme used development vehicles D1 to D4.
D1 and D2 established some of the basic configuration issues, whilst D3 and D4 were used to test the aerodynamics of the design.
The Army rejected the idea of using a liquid fuel rocket because of the difficulty in handling the highly reactive fuel in the field, so a solid rocket sustainer had to be chosen instead.
Several different models of sustainer were tried, most of them known as the "Luton Test Vehicle", or LTV.

While testing of the Red Shoes was underway, the "competition" in the form of Red Duster was also entering testing.
Red Duster demonstrated several serious problems, and the Army ended any interest in it.
In the end the Red Duster problems were sorted out fairly quickly, and it entered service slightly before Red Shoes, as the Bristol Bloodhound Mk.
I.
The production Red Shoes missile was officially named Thunderbird.
 It entered service in 1959 and equipped 36 and 37 Heavy Air Defence Regiments, Royal Artillery.
It was the first British-designed and produced missile to go into service with the British Army.
