Mammut's Mercury IV Mid GTX takes a different approach from the heavy leather boots around it in our ankle-support guide. Amazon lists a synthetic upper, a leather lining, an EVA insole, a rubber sole and a mid-top cut, with Gore-Tex in the name. It is aimed at walkers who want some ankle coverage and a waterproof boot without the weight and break-in of a full leather model.

In its favour
- Listed as a mid-top walking boot, with a cuff that covers the ankle without a tall shaft.
- Gore-Tex is named in the title for a waterproof liner.
- An EVA insole is listed, which adds cushioning on hard paths and long descents.
Good to know
- Water resistance is listed as water resistant in one field, so check Mammut's own page.
- The outsole compound and maker are not named in the listing.
Our take
What Mammut and Amazon list
The seasons field is autumn and winter, and the item type is walking boots. The shaft circumference is 25 cm, and the listed item weight is 1.38 kg, with no note on whether that is per boot or per pair. The country of origin is China.
The water resistance field reads water resistant, while GTX in the name signals a Gore-Tex membrane. The listing does not name the outsole compound or the midsole material.
Synthetic upper, leather lining
Synthetic uppers tend to need less breaking in than leather and dry faster on the outside. Pairing that with a leather lining is unusual; it should feel soft and comfortable against the sock, though it adds warmth, which suits the autumn and winter listing.
Maintenance is straightforward. Brush off mud, rinse, and dry at room temperature. A spray-on proofing helps the synthetic outer shed water so the membrane can breathe.
Mercury IV against the Trango TRK GTX and Kailash Trek GTX
The La Sportiva Trango TRK GTX has a leather upper and ankle cut. It suits people who want a more durable outer and are happy with a break-in period. The Mercury IV is the more comfortable option for those who dislike stiff leather.
The Scarpa Kailash Trek GTX, with suede and nylon, a high-top cut and a listed 585 g, is the closest in spirit. Choose the Kailash if you want a slightly higher cuff and a named Vibram sole.
Who should look elsewhere
Walkers carrying heavy loads off path may want the structure of a calf-height boot like the Lowa Tibet Evo GTX. People who want to resole a boot later should note that the listing gives no construction details.
Verdict
The Mercury IV Mid GTX suits walkers who want a synthetic, Gore-Tex mid boot with a soft leather lining for autumn and winter. If you want leather durability, choose the La Sportiva Trango TRK GTX, and if a higher cut and Vibram sole matter more, the Scarpa Kailash Trek GTX is the better pick.
