Within the first week of wearing these shoes for work (sitting at a desk), the insides were separating from the soles. Now that they are just over 6 weeks old, they have completely disintegrated. The entire shoe has collapsed on the inside. The soles are hollow, formed by ribs under the foot. Those have crushed, and the liner of the shoe has completely fallen apart. The total life of these shoes is under 6 weeks with mild use sitting at a desk. Horrible design, terrible quality. Spend a little more on something worth the value.
