^Where'd you grab those Superga's Kayhill? Their Australian website seems to have closed down and buying from overseas is about a $30 markup from the 60 or so they where sold here for, beat my pair to shit over the summer and looking to grab another for a vacation in June.
I think they would be a bit to full for your liking, looking at your preferences through your 'Chino Journey'. Best thing to do is get to a DJs, Myer or RL that stocks them and try them on (Preston is everywhere in Melbourne, but not too sure about NSW).
I find them priced well, but the friends who I went with have experience with international Uniqlo's and said that price was quite hefty; in my opinion really nice for the price:-nice fit, boxy but not overly so-thick ribs, don't seem like they'll stretch out to badly-just wish grey would arrive soon
^Selfedge, Superdenim as well as Ironhearts UK distribution chain. For cheapsies be sure of your size and hit up Rakuten.
PSA: Uniqlo has crewneck sweatshirts in store (bit pricey at $40) but not online (no greys though), picked up one in a deep navy today.
I wouldn't buy weightlifting shoes if you aren't oly lifting or at the very least squatting, for it would be a waste of money. I'd try using a lacrosse ball (or whatever small torture instrument you have) on the soles of you feet to see if you can work any tightness away.
