US10.5D is my normal size.
Also depends on the shoe last.
For eg. Recent years, NB shortened their last. I got to size up to get the right length/width.
Rebel 1 - 10.5D
Rebel 2 - 10.5D
Rebel 3 - 11D
Rebel 4 - 11D
For Taobao, I believe they suggest according to length.
In general, any size that corresponds to 280mm fits me well.
I can't speak for Plaid 2. But the reviews seems to suggest it's firm + good energy return.
Maybe need to watch the "cutting in" at the arch(足弓). I did get abrasion initially on both Plaid 1 and 1.5.
*Qiaodan customer support suggest sizing half size up for Plaid 2.
Jingtan3 turbo on the other hand is balance of firm/soft + good energy return.
Bonus is can add insole to tilt the balance of firm/soft to what you like.
Edit: I don't like firm shoes so waiting for more Plaid2 discounts and reviews before buying one to try.
Add: Rebel 4 is nothing spectacular. I'd even say lost its identity. Heng bought on discount. But could have used the money to buy another Jingtan 3 turbo!
