Mogano is a mahogany brown colorway of Tempesti Elbamatt Liscio, a vegetable-tanned leather produced exclusively for Viberg by Tempesti, a tannery in Tuscany, Italy. The leather is characterized as a classic Vachetta that is drum-dyed, greased, and oiled with an aniline finish and no surface coating. Mogano starts as a light brown shade and develops into a rich, two-toned patina with orange undertones in the quarters and woody tones in the vamps.
Mogano features the same specifications as other Tempesti Elbamatt Liscio colorways. The leather is vegetable-tanned, oiled, and produced from half butts with an aniline finish and no protective coating. The tanning process includes drum-dyeing and greasing treatments that penetrate throughout the leather rather than coating only the surface.
The leather has medium firmness despite exceptional flexibility, suitable for footwear applications requiring both structure and movement. Open pores in the vegetable-tanned leather absorb oils from hands when touched, causing the material to darken over time. The mahogany brown color results from the drum-dyeing process applied during production at the Tempesti facility between Pisa and Florence.
The Mogano coloration evolves distinctly during wear. The leather begins as a light brown shade and develops into a rich, two-toned appearance through use. Quarters develop orange undertones while vamps darken into woody territory. This color variation results from differential wear patterns and oil absorption across different areas of the boot.
Exposure to air causes the leather to oxidize, impacting the hue over time. The open pore structure characteristic of vegetable tanning allows the leather to absorb oils from handling, accelerating the darkening process. The leather demonstrates notable recovery from surface damage, with grazes and scratches diminishing after brushing.
Viberg offers the Mogano leather on the Service Boot using the 2055 last. The 2055 last is advertised as wide but features low volume characteristics. The last has minimal arch support, a narrow heel and waist, and an anatomical ball and toebox design typical of a Munson last configuration.
The construction uses stitchdown methods with a double row of stitching that attaches the upper to the sole. The standard sole specification is a Dainite Studded Half Sole in black. Pricing varies by market, with one reported purchase totaling 1,400 NZD in New Zealand.
Viberg recommends applying a moisturizing Shoe Cream or Leather Conditioner every three to four months, or as needed depending on environmental conditions. For regular maintenance, clean the surface with a clean cloth or brush to remove dirt. For deeper cleaning, apply Leather Castile Soap, wipe with a damp cloth, and allow the leather to dry fully.
To condition, apply a small amount of Shoe Cream or Leather Conditioner evenly to the uppers using a clean cloth or dauber, then allow to dry fully. After conditioning, buff with a Horsehair Shine Brush. Store boots with shoe trees to absorb excess moisture and maintain shape. New Viberg boots come pre-conditioned and require no additional treatment before initial wear.
