Spenco is a great company that produces high quality, supportive footwear at incredibly reasonable prices. I was never asked to change my review once, which really says to me that these guys have confidence in their product and believe it truly will last. Says it compatible with square tubing but it isnt really. Well, its been one complete summer and late fall now, and the verdict is: success - the item lives up to expectations/hopes. Write a so long review, because i really like it. ?? Before i start , let me tell you that all crocs are made of propietary material called croslite which is a closed cell resin material- neither plastic nor rubber. I looked through many reviews and slippers before I saw this brand in Khols. Im a professional teacher who conducts online classes and video conferencing sessions, so I need headphones with a boom mic (better quality for my students and office mates) and a very comfortable fit (I must wear the headset for 2-3 hours at a time). Peccato per lutilizzo in mono solo della cuffia destra, della mancanza del controllo di volume e dellattivazione dellassistente telefonico dalla sola cuffia sinistra. Have a blessed day!
