Not sure about specifically early 90’s Vans, I remember Lampin being a great Vans style from that period. Vans went through a really weak stage in the mid/late 90’s.
I suspect you mean the Classics range (Old Skool, Era, Authentic etc etc)…any of those are a good bet and have been worn all over the place since the early 70’s.
Purely on the strength criteria, I remember Duffs Strombolies being super tough (back when Duffs were a serious skate shoe company). Axion were great too, I remember the Kareem Campbell model being incredibly tough. My favourite ever pair were the es SLB -Sal Barbier mid-top pro model with the elasticated inner sock.
I hear good things about Lakai, but I often find that there’s a trade-off between strength and boardfeel these days…I don’t know how people can skate in a lot of the Supra shoes.
