The insoles are thin, if you add an insert or anything they might not be able to handle it where the fabric is attached to the bottom of the shoe. Cuffie di qualità ne ho solo una, la DT880 600ohm (precedentemente ho avuto tutte le cuffie Marshall sia in ear che on ear ma non mi hanno mai entusiasmato, anche perche sono arrivato alla convinzione personale che il suono sia piu convincente con cuffie aperte). Thanks Jamal for the little gift to me. I have RA and my feet don?t hurt walking in these Sandals. Probably not recommended, but I have thrown them in the wash, air dried and they were fresh and clean. Not happy because these arent inexpensive so they should wear better than that. Mindblowing light show and sound quality. I need assistance to get the belt on properly, but Im still giving this 5 stars because of its value and comfort! What is going on under the hood that permits this. Know that they are discount store quality.
