Couldn't load pickup availability
The Zephyr MK2 GTX Mid TF in the Wide version is a mid-cut tactical boot designed for those with a wider-than-average foot: shooters, hunters and professional operators who cover varied terrain and cannot afford friction points or lateral instability. The high collar — 110 mm on the inside and 145 mm on the outside — provides ankle support without restricting stride, with a weight of 1,140 g per pair in UK size 8.
The GORE-TEX Extended Comfort membrane manages the balance between waterproofing and breathability during prolonged use: it keeps the foot dry from the outside without building up moisture from perspiration, as a waterproofed construction without a breathable membrane would. The upper in 80% bovine suede and 20% Cordura combines the suppleness of leather with the abrasion resistance of synthetic fabric, remaining flexible enough not to fatigue the foot on long outings. The LOWA Monowrap frame distributes the load outward towards the sole, reducing lateral give on uneven ground without adding weight to the construction.
The LOWA X-Trac Military rubber outsole is certified to CE EN ISO 20347:2012 class O2 WR FO HI CI HRO SRC: slip-resistant on wet and dry surfaces, fuel-resistant, contact heat- and cold-resistant — a compromise that rewards versatility over outsoles specialised for a single surface type. The insole in 90% polyurethane and 10% polyamide cushions without collapsing over time as open-cell foams do, though it is less adaptable than a custom anatomical footbed.
Key features
- The Wide version provides greater internal volume than the standard width, eliminating lateral compression during extended sessions.
- The GORE-TEX Extended Comfort membrane keeps the foot dry from the outside while maintaining active breathability, without the typical compromise of non-breathable waterproof linings.
- The Monowrap frame reduces lateral give on irregular terrain, improving ankle stability without adding stiffness to the stride.
- The X-Trac Military outsole meets the SRC certification for slip resistance and HRO for contact heat, making it suitable for mixed surfaces.
- The mid-cut construction balances ankle support and freedom of movement: it offers more lateral protection than a low shoe, but less than a full-cut, with a compact profile that also suits vehicle work.
