They are made by felting wool felt and are essentially felt boots. Traditionally they come without a sol and worn with 'galoshi' (rubber or plastic cover) to protect the soles from water and wear. I remember wearing Valenki in the kindergarten back in Moscow, so did everyone else 😍 Valenki used to be a traditional foot wear in Russia, but then they became seen as unpractical mostly in the cities.
Today, when we witness revival of ethnic and eco friendly clothing, valenki become a popular choice for bohemian boots for organic clothes lovers.
Valenki are warm felted highboots made from dried sheep’s wool, they are quite soft and get the form of the human's sol. They are traditionally worn for walking on dry snow when the weather is frosty, so they best place for them would be a ski resort ⛷🎿
