Hello, I have a lot of professional standing and hard wearing. On top of that I have overweight (about 140kg at 1,85m size). For some time I was suffering from a sharp pain in the heel inside. After a normal working day, when I no longer have to weigh you down, it's the worst, I can then only hobble. At first I thought I might get it with painkillers in the handle but the thoughts I rejected again. Then I read on the Internet about "heel spurs" and that there are these insoles, however. I wear them for 2 days in size XL (47-49) 3 / 4tel length in my trekking shoes and really have to say, it helps! The pain occurs no longer on the heel and the adjustment period to the deposits is very short. I had to about 9 hours in the shoes already feel at all to wear inserts. I never write reviews but this time otherwise I am absolutely convinced of the product and it is worth buying at the above mentioned problems with the feet is 100%! Very good Footlogics and keep it up!
