    This item saves my life on business trips. I am a passionate boot lover and never find space. Look at that: Only one base shoe and 4 different VIVI models: Leaves me with 4 boot styles by only taking one base shoe. Wohooo love it! Thanks Vivien Sophie

    Acabo de tener una sesión personal de tallas con la propia fundadora. Ha sido muy amable y me ha refrescado la comida en la consulta del médico. No puedo esperar a tener mi pedido en mis manos.

    Um conceito gigantesco. Finalmente, os calçados que estavam parados no meu armário há muito tempo encontram um uso novamente e podem ser expandidos de forma ideal com os VIVIs!

    Kann ich nur empfehlen. Ich war auf der Suche nach einem besonderen Geschenk für meine Freundin. Sie hat sich extrem gefreut und war auch insbesondere von der aufwändig gestaltet und Verpackung begeistert.

    These boot extensions are super super space saving. With only 2 different paris of VIVIs and 2 different base shoes I am able to combine 4 completely different looks !!

    Es gibt viel zu wenig Mode Marken, die so einen tollen Stil haben und sich auch mal nach den kleinsten Frauen richten. Ich finde es toll wie diese deutsche Modemarke ihren kompletten Fokus auf das Thema Frauenpower lenkt. Ich bestelle gerne jederzeit wieder und bin schon riesig auf die neue Kollektion gespannt.

Why we developed Variable Boot Legs?

Because over 85% of shoe buyers face the problem that the shaft is too wide and slips on the leg or is too narrow and digs in. We’ll help you get the perfect boot!

The Benefits of VIVI® in contrast to conventional boots?

VIVI® is a shoe topping that turns any of your own shoes into a perfect variable boot! And the best part: you choose between different lengths & widths!

Highest Comfort & Style!

We use materials that are characterized by a high proportion of stretch that nestle particularly well to the silhouette of the leg. Particularly positive is the supportive compression effect which comes along with the leg-hugging fit.

Innovative materials

With us, animals do not have to give their lifes! We will increasingly use sustainable materials such as cactus, apple or tea leather in order to play a pioneering role with our VIVI® s, also from an ecological point of view.​

Finest Craftsmanship from Europe

Strictly speaking, each of our VIVIs is unique as the processing requires finest manual work! Our VIVI® s are made in Katowice, Poland, by experienced seamstresses using the latest sewing tools. ‌


Yes, the VIVIs are variable boot toppings that can be put on any shoe you like.
Definitely! We offer VIVIs in many different lengths and widths so that everyone can find what they are looking for. There is the option to order short wearing versions for all VIVI models.

If you are interested in short boots or VIVIs that end below the knee, then you have to order 2 lengths shorter than what is recommended in the size generator for over the knee. Example: The size generator recommends length M, then you have to order length XS for a pure below the knee model.

Yes, any over the knee VIVI can also be converted into a below the knee VIVI by folding the VIVI in at any point, or pulling it down a little overall. For a pure below the knee look, however, we recommend ordering two lengths shorter. 
If you don’t want people to see that your boots are made up of two parts, namely the VIVI and your shoe, then we recommend that you take shoes that go up to the ankle and are as close-fitting as possible. Another tip to create a perfect transition between the shoe and the VIVI is to choose the shoe in the same look as the VIVI. With our first collection, this is quite easy because all models are black only.
With our first collection, this is quite easy because there are only black models, each with different looks: from smooth leather look to velvet to high gloss.
The VIVIs can be easily wiped with a damp cloth or be dry cleaned.
Yes, we will take care of the shipping and return shipping for you!
