Quality standards

Due to the handmade production processes, some deviation from the standard parameters is inescapable. However, for each production process, quality indications are defined and checked during each stage of production. Such verification is complied with the international quality control system.

Internal quality standards for felt shoes:

 

Shape: For compliance with the shape and size, each pair is measured and checked by special markings on shoe lasts.

 

Density of felt: The standard is 0.27-0.28 gram / cm3. There are standardized thickness and weight measurements for each pair of felt slippers. The standard thickness for wet-felted slippers is 6.5 mm. The standard thickness for sewn slippers is 5.5 m. The soles of sewn slippers consist of two layers of felt with 4.5 mm thickness.

 

ColorDue to the handmade processes of production and use of heat and water, we allow 0-5%deviation from the reference color in Pantone TPX system. The quality of the applied dyes is determined by resistance to wet and dry methods of abrasion.

 

Gluing: The quality of gluing work (attaching a leather or rubber outsole to a slipper) is subject for external inspection and selective testing by twisting and tearing. All types of soles, except for rubber, must be stitched additionally around the perimeter of soles. The quality of glue and sole materials must be confirmed by quality certificates received by a supplier.
