Optionally, instead of joint knot, the continuous static dissipative material 50 without any open end is formed using single split ring 80 and the sub- electrostatic dissipation loop of biobelt is automatically become, such as Fig. 3 (b) and Fig. 3 (c) are shown.This is to form the most simple designs for the non-open end knot that only one single-piece split ring and a single-piece electrostatic dissipation belt are used during the high impedance of non-ESD footwear or resistance in more than 35MO discharges the electrostatic dissipation loop of footwear.

The sub- electrostatic dissipation loop of biobelt is preferred.The different advantages of biobelt subloop, which there is provided the electrostatic dissipation loop when the entanglement that one of described loop is easily noted that due to uncertain abrasion and tear and in a large amount of labours in extensive assembly operation is damaged, needs the early warning for changing or replacing to represent.

The same procedure on possible various combination descriptions can be also used to be readily constructed the sub- electrostatic dissipation loop of two or more biobelts without departing from the present invention.

Non- ESD footwear or resistance of Fig. 4 (a) displayings with the electrostatic dissipation loop being bonded together by two split rings 80 discharge the cross-sectional view of footwear in more than 35MO high impedance.Split ring 80 is positioned over the outside that non-ESD or resistance discharge footwear footwear in more than 35MO high impedance.This loop design shockingly possesses at least four particular advantages：

1）It, which allows simply and readily to change or replaced, wears bad static dissipative material 50, especially with the lower loop due to high fretting wear caused by daily Ambulatory Activity etc. and tear.

2）It allows the upper part in static dissipative material 50（It is not subjected to high abrasion and tear is used）It is upper to use softer and relatively thin static dissipative material（Such as material based on rubber）, to provide user's comfortableness when user tramples on the top of inner sole.

3）It allows to use different materials in electrostatic dissipation upper and lower part loop is formed.For example, high abrasion static dissipative material may be selected to be used at the low portion of loop, to dramatically increase its durability and serviceable bife to obtain significant economical advantage.

4）It allows the more accurate control to the resistance from body to the earth.This can be accomplished by the following way：Connection ring is made by hand with being simply configured with two（As shown in Fig. 4 (b)）Calibration resistor 90（Such as 1 MΩ）The split ring at the extreme rear portion of the heel wall of footwear is replaced, and uses dead ring（Such as nylon ring）Replace the split ring 80 at the bottom of sole.If the resistance of both electrostatic dissipation upper and lower part loops is respectively less than 0.5 The resistance of M and resistance 90 is 1 M, then the body as described in Fig. 4 (c) will be in only 1 to 2 M to ground resistance, and it is the ideal resistance scope dissipated for the electrostatic charge from body to the earth.

Optionally, the split ring 80 of the original central spot for being positioned at the surface of bottom sole 40 can be repositioned at any point of static dissipative material 50 along the surface of inner sole 35 in footwear.This arrangement will minimize dust at the bottom of sole 40 around the region of split ring 80 or particulate trap or accumulation between walking active stage, to minimize direct pollution or cross pollution in especially clean room.

Non- ESD footwear or resistance of Fig. 5 (a) displayings with the static dissipative material 50 being bonded together by two split rings 80 discharge the cross-sectional view of footwear in more than 35MO high impedance, there is the additional openings ring 80 at the vertical circuit footpath of extension, top inner wall of the power path to discharge the rear end region of footwear positioned at non-electrostatic to terminate for it.When the Electro-static Driven Comb shoe cover with electrostatic dissipation or conductive edge of opening as shown in Fig. 5 (b) is used together, the vertical circuit footpath of non-ESD footwear is electrically connected to the high impedance release shoe cover 95 of ESD footwear or resistance in more than 35MO to form the connection network as shown in Fig. 5 (c), to draw electrostatic charge to the earth from body when personnel station is on electrostatic dissipation or conductive floor.

Optionally, when putting on the Electro-static Driven Comb shoe cover 95 of particular design shown in such as Fig. 5 (d), the split ring at the extreme rear portion of the heel wall of footwear can be replaced by the connection ring of making by hand formed from resistor, and to insulate（Such as nylon）The split ring 80 that ring replaces at the bottom of sole will realize 1 M is to 2 M body to ground resistance.
