As has already been mentioned here several times, the sole or the 'memory foam' is not as soft as in other Skechers models. Since the manufacturer's shoes are a bit too small for me overall, I usually have size 43 and need 44 here, and 44 is a bit too high, so an insole with 'memory foam' helped. From this point of view, the price reduction to 40 euros is possible. The insole cost 15 euros. I kept the shoes because I thought the total price of 55 euros was reasonable.
