I have been suffering with tendinitis. bon produit, facile d’installation. I purchased this so I can use gsp / mapping to track my bike rides. What an amazing product! Wish it wasnt USB without adapter, but I have ports available. Let me start this review by saying I do find these shoes to be a great product, Just not one that met my needs. Will keep them to the side as she’ll grow into them eventually. It does not pick up my voice at all. I need a supportive sole and nothing flat. I was skeptical because of how low the price was but im so happy with the turn out!
