Two styles with the same ESD function and SPU sole; choose by ventilation.
Both slippers have the same ESD function and SPU sole; the only difference is ventilation holes in the upper. The closed-top style covers the foot well and is used in temperature-controlled cleanrooms. The six-hole style dissipates heat better in hot workshops or on long summer shifts. If your plant is temperature-controlled, the closed-top style covers most needs.

About SPU
SPU (super-soft polyurethane) combines the cushioning of foam with the grip of rubber. It feels soft underfoot and reduces foot fatigue during long standing. The anti-slip tread grips on ESD floors and tiles, and the material is low-shedding for cleanroom use.
Buying in bulk
For company purchases, first count staff foot lengths. Most orders center on sizes 38–42, with a few pairs in size 35 and 44 and above. Replace slippers every 6 to 12 months, sooner at busy workstations.
