I cracked the arches after 3 days
The soles are supposed to support arches but after just 3 work days I've flattened them out. They felt good at first, nice and firm. That lasted for about 5 hours. Ever since they would only regain their stiffness after I took my shoes off during my breaks. They never returned after day 3's last break. This is with working on a concrete floor in 8 hour shifts however.
