Build was quick and easy. way too wide and long for the stated size. Plus its just a generic, plain cap. The second outburst was it. I ordered these on 1/14/2020 they was delivered on 1/19/2020 I can truly say i am a very happy camper and they are exactly what i wanted and was looking for they are so comfortable so far so good I wear a US size 7 because they are made in China so i purchased a size 8 i wear a size 37/38 in chinese size because they run smaller than American made shoes so i always go up one whole size when i buying any shoes made in china Im dropping to 4 stars because of the color and the fit being not quite at 100%. I love Roxy sandals. The battery last a long time during the day and I have had zero issues. The stitching seems too widely spaced and to be done with weak threading. The Duet BT is highly recommended.
