The Madrid Eva sandal of Birkenstock brand is a classic one-strip sandal that’s waterproof and super lightweight which great for the gym or the beach. For the Madrid Eva sandal, it has many colors from light to dark tone of color and the special design that are not same as other brand but for the price estimate thousand ends up to two thousand. The heart of all model sandal is a Birkenstock footbed that helps your feet feel as comfortable as possible for hours on end and also supports health and promotes wellbeing. The very deep molding in the heel area supports the foot tissue and holds the heel bone firmly in its natural position. This version helps to activate the calf muscles, stabilizes the back of the foot and improves gait and coordination, and also supports the middle of the footbed stabilizes the metatarsal bone. There are raised indentations at the front of the footbed near the toes that supports the natural rolling motion of the toes. The Eva is a high-quality, very light, elastic material with very good cushioning. As a result, it smooths out slight irregularities in the floor and ensures that every step is softly cushioned. As for the details of the information and my experience, I think its very very good sandal I ever wear. For the early that I buy and wear it at the first time, I feel hurts and have a little wound because this Eva will change the shape of the feet to be the correct posture when I’m walking or running. And when I wear it for around 2-3 weeks, it’s not hurt anymore because I wear this sandal every day and my feet shape is better like I can stand and walk more than an hour or 5-6 hours in a day. The Madrid Eva is a sandal that’s supporting every gender and every age because it’s a kinda healthy sandal. So, I think it’s worth to buy and also worth to your healthy despite its average-to-expensive price point. I recommend these sandals to anyone who wants to wear for daily usage outside, it’s better than normal sandal from any other brand. You may not be disappointed for buying this sandal brand.
