I have 3 pair of genuine Birkenstocks size 37. 2 tan ones,1 black. Only worn a couple of times I realise I bought them too small and need 38. The tan 2 strap ones I am selling for $120 as they are the more expensive genuine LEATHER with the soft foot bed. The other 2 pair selling for $100 EACH PAIR.I'm gutted as I will now have to buy same one in size 38 and pay tax which the buyer of these won't have to.I paid $149.99+ tax for the leather ones and $129.99+tax for the other 2 pair.My loss your gain. Price is fixed FCFS, no holds.
