First, what’s SB?
 
SB is the exclusive mark of Nike skateboarding shoes.
 
How to identify the SB and general retro shoes? The following is to talk about the difference between them.
 
From the category terms,first SB is skateboarding shoes, LE is basketball shoes. Although they both adopted the original style, there are differences in nature.
 
Seond, each section of SB series has a strict control on quantity, so, the value is usually higher than ordinary one.
 
From the appearance and performance terms, take DUNK series as an example.
‘
First, it is sewed a “NIKE SB” logo on the tongue of SB shoes, but it is only marked “NIKE” on the tongue of ordinary DUNK shoes. In addition, the mark of Air Force 1 is “NIKE AIR”.
Second, still tongue. DUNK of SB series is usually several times the thickness of an ordinary DUNK, which is designed to protect the skateboarding athlete's ankle.
 
From the shoelace term, ordinary DUNK uses wide-textile shoelace, while the SB uses thick shoelace.
 
Third, the insole. Ordinary DUNK is marked “NIKE” and its swoosh logo on the insole and DUNK or LE series is marked “LE” on the insole. However, different from the previous two, all SB shoes are marked footprint scratch on the insole, on the heel of the footprint is marked “NIKE SB”. In addition, under the insole of SB shoes is attached two zoom air. It is naturally for comfort and safety.
 
Fourth, there are more than 10 grooves at the edge of the outer end. In fact, the other skateboarding shoes such as DC, Timberland, also have such groove. This design is mainly for jumping and carrying up the head of the skateboard by feet. However, the original edition of DUNK generally do not have such groove.
 
The last, there is normally knitted logo related to its identity on the outboard of DUNK SB’s heel. This involves a deeper question which is the SB system that launched by each street brand and Nike.
