They are not that comfortable. I wear these when I need to be a bit dressier and want to look like Im not wearing orthopedic shoes. Grand Tour was back in all its 4K goodness. Mouse dimensions are L124xW65xH43mm. Wearing Crocs with socks is like wearing sandals with socks, wont do it, but the lining keeps my feet nice and warm! He said they stay on during his work out even while hes sweating. I loved the fit and the style. Another issue: spring clip that holds earpieces in is very loose. I can walk quickly easily and they feel stable. Thank you it was just what I needed and then some.
