LOWA Zephyr MK2 GTX LO Boot — Black

The Zephyr MK2 GTX LO is a low-cut technical shoe by LOWA, designed for those who cover demanding terrain in variable conditions and need waterproof protection without sacrificing breathability. The upper has an internal height of 80 mm and an external height of 115 mm, with CE certification to EN ISO 20347:2012 in classes O2 WR FO HI CI HRO SRC. Weight is 1.02 kg per pair in UK size 8. This is the Regular version, built for standard-width feet.

The GORE-TEX Extended Comfort membrane strikes a precise balance: it is more breathable than standard GORE-TEX membranes while remaining fully waterproof. On long outings or during sustained high-intensity activity, the difference becomes noticeable in internal moisture build-up. Those who move slowly with cold feet will benefit less than those who move dynamically and generate heat. The waterproofing is genuine, not merely surface water repellency: the foot stays dry even with partial immersion when the shoe is laced correctly.

The upper combines hydrophobic suede leather at 1.4–1.6 mm with CORDURA nylon — a combination that balances lateral abrasion resistance with overall low weight. The dual-injection polyurethane sole forms the LOWA-Monowrap frame, which wraps the entire shoe to provide torsional rigidity without restricting longitudinal flex: the foot lands naturally, yet the shoe does not twist on laterally unstable ground. This structure reduces lateral muscle fatigue on long outings, but does not replace the ankle support offered by a mid or high-cut model.

Key features

• GORE-TEX Extended Comfort membrane: full waterproofing with superior breathability over the standard membrane — useful during medium-to-high intensity activities.
• Hydrophobic suede upper at 1.4–1.6 mm with CORDURA reinforcement: laterally abrasion-resistant without unnecessary added weight.
• LOWA-Monowrap frame: integrated torsional rigidity that stabilises the foot on uneven ground without restricting the natural flex of each stride.
• Low weight of 1.02 kg per pair: suited to those who need to cover significant distances without the footwear itself becoming a burden.
• CE certification EN ISO 20347:2012 O2 WR FO HI CI HRO SRC: meets safety requirements for professional use in environments demanding thermal protection, oil and hydrocarbon resistance, and grip on wet tarmac.
• Regular version: built for standard-width feet, not suitable for those who require a wide fit.
