Mammut Pro

The tried and tested Standard last provides an optimum fit, and the synthetic leather upper keeps stretching to a minimum. The pretensioned heel combined with the midsole imparts the right amount of sensitivity and edging stability. The quick-lace system and two pull-straps make the shoe easy to slip on and off.
Sole: Vibram 4 mm

Standard last:
The classic. The standard last has a higher instep, a barely tensioned heel and a classic, lightly asymmetrical shape, providing maximum sensitivity for wide feet, or when the Radical or Asymmetrical lasts are too tight.
