Shoe was perfect otherwise. My use its not really a problem but if it was in and out of a pocket regularly for example, dont think it would stay on? For me not issue, it lives in a car and come out when time to remove buds. This bike phone mount hols the phone securely and is easy to use. Arrived as described, and exactly what you?re looking for if it?s an iPhone and uses the usb-c type charger. I liked the sleeves as it was a November event with temperatures in the low 40s F.

I need to know when Im taking them off whether i need to charge them before the next run! I?ve bought different earbuds from amazon and most of the time they are usually have a not so good sound or bad build quality. I?ve been using Fitflop for many years and have sandals (in lots of colours), clogs and boots.
