Smart black jeans, not skinny

[BalmyBalmes]

Can anyone advise where I may get smart black jeans, not denim but jeans style trousers.
I'm early 50s, size 12. Don't want skinny jeans but looking for very slim cut. All the straight leg ones are wider on lower leg than I'm looking for. Want to be able to easily tuck them into long boots in winter. Budget is up to £70

Ones I currently have were from Wallis. I miss Debenhams where I could go to all the different concessions under one roof and usually find something. M&S don't have anything suitable. Everything I've seen in Next is either too skinny or too "jeans" like

TIA

Massimo Dutti

I think River Island had some but might be too skinny for you.

Lindex online have a great selection, the quality and cut is much better than Next etc.
£35-£60.

Levis 524 or 724

Try Hobb's Amanda Jean. They are above your budget at £89, but could be worth a look. Cut like jeans but not denim.

Gap

I bought these a couple of weeks ago and I am loving them.
A bit thinner than normal denim and stretch.
