| Notes | Peterson 572 is a reliable electronic LED flasher in the classic round 2-prong format. It provides a consistent flash rate even with low-draw LED lights (unlike older thermal flashers that often hyper-flash with LEDs). Simple plug-and-play installation makes it a popular choice for fleet upgrades and aftermarket LED conversions. | ||

Footbed very soft and cushiony
Size: 9, Color: Sand
It was so comfortable even though it was a half size too small so i was able to exchange for a larger size. I originally ordered a size 9 and exchanged for a 9.5. I haven’t received the 9.5 yet but I am sure I am going to love them. They are so cute and go with everything.

I wanted to love these....
Size: 8, Color: Sand
I really wanted to love these, and I *almost* did. They are comfortable and cute. But they are a little wide across the mid-foot so they were a little sloppy on my feet. The platform is quite high, and while at 5'3" I appreciated the extra height, between that and being too wide, I felt they were an accident waiting to happen. If they were slightly more narrow and a little lower, I would have been in love, but I had to return them. They seem true to size except for the extra width.

Comfort in a Slide
Size: 7.5, Color: Black
These are true to size and extremely comfortable. I prefer the extra height that they provide and the quality is 10/10. I would purchase in another color and highly recommend them if you’re looking for these attributes in a slide.
