Do you have to ties the laces or are these slip-ons? The pictures are not consistent.

Considering buying these from seller 'one nation premium'.. has anyone purchased from them? is it the real Sperry shoe or a knockoff?

What size can I order if in most shoes my number is 38 - 38 1/2 European, in adidas I am 7us?

the ad shows 10 1/2 but it does not say which width. how can i purchase if they do not specify width
