Lake shoes help sought

I have relatively wide feet and a high arch and I'm looking at a couple of models of Lake (road) shoes. Don't want entry-level shoes (prefer stiff/carbon soles), but don't want to break the bank either. The CX 238 looks like a good choice. Any input on this model would be most helpful!

Lake's fitting guidelines drive me batty--I *think* I need size 40.5. Does anyone out there in CyclingChat have a pair in this size (either standard width or wide) and are willing to provide the actual measurements of the insole length and width?

Also, I stumbled on a mint pair of the original version of the Lake CX 400 shoes--purchased 8 years ago and never worn! I am fascinated by the heat moldable feature, but... does it really work? I know the CX 400 has been updated this year ($349 msrp), but this might be a chance to grab a pair for a bargain. Any thoughts at all on this earlier model would be greatly appreciated! Thanks for your wisdom and stay hydrated out there!

Here's a link to an early review (with pix) of the original CX 400 from Cycling News:
