Not stiff or tight…
Size: 13.5 Little Kid, Color: Turquoise/Multi
My niece loved them. So many of the slips in shoes are too stiff and tight, this one was easy on, not stiff or tight, just perfect!

Good hub if you're missing an ethernet port and want one
Bought this for my laptop that lacks an ethernet port. The connectivity is perfect. Have had it now for over 6 months and no issues; not surprised as it is an Anker (always reliable for me). Nice to have an extra USB-C port, as well as 2 USB-A's. Haven't used the display port, so can't comment on that. Nice and compact.
