With the Sienna your feet will always want it to be Autumn.
Why?
Because they make them have the prominence they deserve.
They are protected, comfortable and naturally able to move freely.
But if you want to know more, I'll tell you everything below.
Groundies Sienna
The boot that will make your feet wish it were fall every day of the year
You get up in the morning to close the window and notice how the fresh air comes in through it.
A louder than normal air hiss.
One that refreshes your face and tells you that that long-awaited moment has arrived, your favorite time of the year: autumn.
Time to wear thick socks, your favorite sweater, peace of mind and where time passes slower.
And on your feet, you also want that comfort and warmth. So that the sensation is complete.
But however, when you put on your conventional boots you get the opposite:
A scratch here.
A blister there....
But when you change it for the Sienna, your feet feel that comfort of being at home in autumn but on the street.

How do you activate this sensation in your feet?
Having the shape of a foot and NOT a boot:
- Wide last: so that your fingers have room to move freely.
- Flat (without heel elevation): so that your body is in a neutral position and without tension throughout the day. Making the weight distributed over the entire surface of your feet (and not in the toe area) and your ankles are more stable, avoiding unexpected turns that end in sprains and strains.
- With a sole that allows you to Feel: so that your feet when touching the ground receive the signals and land in a softer, more natural and fluid way. Stimulating them and recovering the important connections between the foot and brain that have been lost due to the use of conventional footwear.
This is the key that allows your feet to remain young at all times.

The longer you use them = the greater the benefit.
That is why its simple lines and soft colors make it very easy to combine every morning with any clothing and go out to do what you like most: walking, traveling, dancing...
They will always look good on you.
In addition, feeling every step will give you the confidence and peace of mind that you are in control, making you always comfortable and ready for anything you propose.
Life begins at your feet!
