The waterproof elastic wraps the leg with a perfect fit, and the grippy sole gives you confidence with every step.

Features of Green Master® boots

Unique sole design for excellent grip

Ever walked on freshly watered grass or a muddy trail? With Green Master®, you stay steady.

The flat, heel-less soles respect the terrain, and the anti-slip pattern supports you on every surface.

A smart touch for those who work with care for the environment.

100% waterproof

Rain won’t be a problem anymore. The technical material used in the upper part of the boots is completely waterproof: no drops, no moisture, just comfort.

Ideal for those who spend hours outdoors or want to go out without fearing the weather.

Slip prevention

The anti-slip band fits the leg precisely, ensuring stability and safety with every movement. You can work, walk, explore without worrying about losing balance. A small detail that makes a big difference.

How to measure your foot

Before starting, wear the socks you’re most likely to use with the boots you want to buy.

● Place your foot on a sheet of paper and trace the outline
Sit on a straight chair with knees bent at 90° to the floor (it’s best to place a white sheet of paper on a flat surface).

* Measure your foot in the evening

A. Foot length and width

Use a ruler to draw two lines connecting the furthest points: the length from heel to longest toe and the width at the metatarsal joint.

* Foot length is the most important measurement to choose the right size.

We recommend measuring both feet—it’s not uncommon for one to be slightly larger.

Always refer to the larger foot when checking size charts, and avoid measuring first thing in the morning.

B. Calf
Measure the widest part of the calf (35 cm from the floor).

C. Height
Sit on a straight chair with knees bent at 90°. Measure the leg height from the floor to the crease behind the knee.

* If you want a bit more room for your feet, we recommend ordering half a size up or using an insole.
Example: size 42.5 → 43
