Shoes that is too large / wide for your feet will cause blister as your feet literally slide inside the shoe sometimes.
I got blisters wearing asics gel rocket. I find the insoles rough. My feet got blisters first few days wearing it. I did not like the material at all. You should test the soles material too before buying.
You should try yonex 3d ergo socks. The ankle is designed 90 degree to prevent the sock from being loose. That would help to prevent the blisters.
Some of the Yonex wide profile shoes still have the Ergoshape profile, such as the SHB-82WMD. http://www.yonex.co.jp/products/badshoes/shb82wmd.html The current highest graded model however has Quattro Fit. http://www.yonex.co.jp/products/badshoes/shbsc6wm.html
