Belt + Armor are definitely best from the list and are used in Gm Melee duels. Belt is for Barbarian whirlwind build as vasya said and armor can be used on all melee characters.
Boots are funny looking but honestly, are only for fun collectors
because 213 Defense 15% Deadly Strike Gorerider are ultimate melee boots in the game (also cb ow)
Pelt is again as you said funny but no real use without 2sockets missed.
Make FT topic to sell items today.
Make Start price on each item and let people Offer you in topic theyre bids/bins.
I would make this, just my opinion so nothing sticky ^^
1. Start 50fg (ft can be close to start maybe ^^)
2. Start 100fg (ft can be 500-1000+ maybe more maybe less im not barb player anymore so ask barbarians friend

)
All i can say is that 40str requirements is very goood
30 Strength is Max add (24fhr is max add)
And 285 Defense is Perfect Roll for 197% Ed on this item

3. and 5. as i said i dont see any usage on those boots.
Girerider upg or Sandstorm trek eth rep >
4. Start 500fg (ft can be 1000-2000 i think)
Gl!
