All day on my feet with a concrete floor. I tried other brands that are more popular and common in the US, but after a short while they were all causing me pain in my legs. I bought them on the recommendation of my mother who had problems with her feet. Most of the people I work with have never heard of this brand, but it's the best I've ever worn. I wear them not only to work, but every day when I leave the house. I am a size 43 which is perfect for my 9.5ft. I bought my first pair from a big store just to make sure they would fit and wore them for a year before ordering the exact same pair online.
