I’m a Birkenstock convert. Last year I lived in my cream Gizahs, and have bought several pairs of Arizonas too ready for summer (although I’m already pootling in the garden with them)!
If you’re ok with it, I suggest buying a second hand pair and see how you get on as they’re not for everyone. I’ve had great success buying very light wear pairs for under £30 on Vinted and eBay, and have even snaffled a pair for under a fiver (which just needed a good clean, disinfect and polish & a little glue on the heel where the bonding had been trodden down).
One of my bargains has been a pair of Arizonas made from a croc-like material which are much softer which could be an option if you think the cork sole may be too hard.
Definitely join the Birkenstock mailing list too as there have been some great discounts over winter.
