The cost of them may be a little high compared to other insoles but the quality of construction and the comfort they offer significantly outweigh cheaper products. I will soon buy a second pair.

Just put them on, haven't had them for a day yet but I suspect it's the best purchase I've made by far.

A little hard and inflexible at the beginning, but they relieve from incorrect foot posture and correct the foot's position. My husband gets much less tired at work with proper posture. They could be a bit more affordable.

I got them for the kids, and at first, I would ask them daily if they ever felt any discomfort, and they never complained. In combination with slippers from the same company, we have already started to see positive results

Excellent construction. For wide feet, I would have liked it to have a larger "arch support" at the arch point. It provides very comfortable walking and is worth its money. The best currently available, and it would be good to prefer insoles that embrace the entire foot, as half insoles for wide feet usually slip and move during walking inside the shoe

Very good quality, they are a bit harder and inflexible. I am satisfied. The 4th pair I order. I also have 1 birko active but only in sports

I have been having a problem with flat feet for 12 years now and usually nothing satisfies me except for quite expensive custom-made shoes. These might be the best ones. I am looking forward to seeing how they hold up over time.
