For workers who already use the XTLZBK Black and want another pair in the same style and fit, remaining stock provides an opportunity to secure this discontinued model before availability ends.

DISCONTINUED – LIMITED STOCK REMAINING

The Bison XT Black XTLZBK has been discontinued.

Supply Solutions Group currently lists this model as:

DISCONTINUED – LIMITED STOCK REMAINING. (Supply Solutions Group Pty Ltd)

This means:

• Only selected sizes may remain

• Some sizes may already be unavailable

• Stock cannot be guaranteed until an order is confirmed

• Further manufacturer replenishment should not be assumed

• The product will become unavailable when remaining stock is exhausted

Black Leather Upper

The XTLZBK is the:

Black

colour variant in the Bison XT Zip Side Lace Up Safety Boot family.

Bison confirms the upper material as:

Leather. (Bison Workwear)

The same original XT platform was also available in Stone (XTLZST) and Wheat (XTLZWHE). (Paramount Safety)

Lace-Up Front with Side Zip

The boot combines:

Lace-Up Adjustment + Side-Zip Access

The lace system allows the wearer to establish the preferred fit, while the zip provides faster entry and removal during day-to-day use.

This can be particularly practical for workers who regularly change footwear when entering:

• Site offices

• Clean areas

• Vehicles

• Accommodation

• Controlled workplace environments

Steel Toe Cap

Bison specifies a:

Steel Toe Cap

for the XTLZBK. (Bison Workwear)

Steel toe protection helps address appropriate workplace hazards associated with falling or dropped objects.

The boot should still be selected according to the site’s footwear and PPE requirements.

Bison Grip Nitrile Rubber Outsole

The XT uses Bison’s:

Bison Grip Nitrile Rubber Outsole

with a:

Multi-Directional Tread Design

The manufacturer states that the wide-fit sole sizing helps maximise surface-area grip while minimising rub zones and trip hazards. (Bison Workwear)

Heat Resistance up to 300°C

The nitrile rubber outsole provides manufacturer-specified protection up to:

300°C. (Bison Workwear)

This specification relates to the outsole’s performance and should not be interpreted as meaning the complete boot or wearer can tolerate continuous exposure to a 300°C environment.

IMFLEX Anti-Penetration Insole

The XT incorporates Bison’s:

IMFLEX Anti-Penetration Insole

The thermoformed construction is designed to improve comfort around the heel-strike area while providing up to:

20% more flex across the forepart of the foot. (Paramount Safety)

This combines underfoot penetration protection with greater flexibility than a conventional rigid protective insert.

Lightweight EVA Midsole

Bison specifies a:

Lightweight EVA Midsole

designed to provide improved flexibility and impact absorption. (Bison Workwear)

This can improve comfort for workers who spend substantial periods:

• Standing

• Walking

• Climbing

• Working on hard surfaces

Four-Layer Heel Support System

The XT incorporates a:

Four-Layer Heel Support System

designed to enhance heel and lower-leg stability and help prevent ankle roll. (Bison Workwear)

This can be especially useful in environments involving uneven ground or substantial walking.

Ergonomic Rocker-Bottom Sole

Bison uses an:

Ergonomic Rocker Bottom Sole

designed to aid forward motion, reduce wearer fatigue and reduce the risk of toe trips and heel-strike slips. (Bison Workwear)

Self-Dispersing Venting System

The XT incorporates:

SDVS – Self Dispersing Venting System

within the footbed.

Combined with the breathable lining, this system helps enhance heat dispersion and reduce moisture inside the boot. (Paramount Safety)

Moulded Footbed & Athletic Arch Support

The moulded footbed includes:

Athletic Arch Support

and compression-resistant cushioning to improve support during extended workplace use. (Bison Workwear)

Thermo Performance Support Foam

Bison’s:

Thermo Performance Support Foam

moulds around the wearer’s heel to provide more personalised support and fit. (Bison Workwear)

Abrasion, Heat & Chemical Resistance

Bison identifies the XT as using durable materials providing resistance to:

• Abrasion

• Heat

• Chemicals

• Organic fats

• Oil

• Acid. (Bison Workwear)

Actual chemical compatibility should always be assessed against the specific chemical concentration, duration and workplace conditions.

Electrical Hazard Resistance

The XTLZBK is certified for:

Electrical Hazard Resistance – ASTM F2413-18 Section 5.5. (Bison Workwear)

Bison specifically notes that EH footwear is designed to reduce hazards from accidental contact with live electrical circuits and is intended only as secondary protection.

It does not replace:

• Electrical isolation

• Lockout procedures

• Insulating equipment

• Task-specific electrical PPE

Safety Standards

The XTLZBK is certified to:

AS 2210.3:2019 – Licence BMP 708413

and:

EN ISO 20345:2011 – Licence BMP 708414

with the classification:

Class 1 SBP, SRC, FO. (Bison Workwear)

Because the product has been discontinued, these are the original manufacturer sizes and should not be treated as current stock availability.
