UPDATE: After wearing them for a full day of errands, the strap on one of the shoes kept coming undone - oddly, the strap has snaps on the exterior of the shoe (as you would expect for an MJ) but also on the interior; it was the interior snap that was coming undone. Fits securely once you slide the bike grips to the right spacing and I was able to use the bike rack lock cable to securely lock the two units together. Also be aware that the picture with the back strap is only on the toddler size. I like that they are available in wide because my son has wide feet for such a little person. That means after the camera has been screwed on that you secure it with also tighting the base. Id take a photo, but he has worn them in the ocean, in the garden, during his daily bike rides, while working with his honey bees, & on the black top during several street fairs. There really might be some fairy dust in them. Build quality is not great, but not terrible. You wont go wrong with this purchase. It will attempt to reproduce that effect by alternating colors on either side, and the color bleed/mixing along the cable will sort of look like a rainbow effect, but its not really that good.
