If they've got TCS Speed boots in black @ £88.95 I'd say get some as thats a damn good price.
They're the latest version of mine (mine all black, no white no silver (apart from toe sliders)) & like I said I paid around £150 a few years back and they're still going strong.
As Clutchmonkey says, they're comfy enough to walk around all day in.
OK they squeak, but leathers also creek / squeak - goes with the territory and you could smell of worse things than WD40, Mr Sheen, Pledge or whatever - A lot of bikers still do, smell of oil / petrol etc that was what bikers did, especially with old Brit bikes - LOL.
Could be worse, could smell of goddamn awful feckin' Patchouli oil !!!!
As I said they do come with a wee bottle of Silicon lube.
Not tried the sharpe knife adjustments myself - afterall, the 'joints' are there to help prevent your own ankle joint moving in an unnatural direction if you come off.
I've not owned Sidi boots before so can't comment on their pros and cons if any, but a cursory look on WWW suggests that the TCS come in very favourably on price compared to Sidi Vertigo if you're on a budget.
go round your local bike shops nd try a few different makes and models on, see what you're comfortable with.
At the end of the day matey you pays your money and makes your choice, but from experience, I'd buy again.
