I had one pair of these shoes before and found them comfortable. This time I bought two pairs. Opened one box and started wearing one pair. Build quality is still good. I find the flap below the velcro straps on my right foot slipping left. The strap then slips to the inner side of my foot that makes it very uncomfortable. It appears as though the shoe maker did not align the flap correctly before stitching. Whilst I like the material and build quality of the shoes, I feel disappointed with the carelessness of the shoe maker and all those involved in quality control to the point where the product reaches the consumer.
