Shoe Help

I have been using 2012 S Works MTB shoes since new and they have been great. I replaced the boas earlier this year and now the lugs could do with being replaced, however it can't find anywhere with stock for a size 44. One helpful shop tried Spesh and they have discontinued them. So i decided to treat myself with a new pair so got these delivered this morning https://www.cyclesurgery.com/p/speciali ... 8.124.html
Thought it was a great price and should basically be a newer version. Take them out of the box and it is instantly noticeable how much thinner they are. Tried them on and they were very tight around my toes. I know i have wide feet and Spesh are necessarily known for wider shoes but i didn't think they would have changed that much. Needless to say i took them back for refund.

I am essentially looking for a super stiff carbon sole (i use them on my race road bike too), i want boa and something that is a bit wider. £150 - £200 budget, unless i am getting something very special for going over £200.

Appreciate any help you can offer.

Thanks

Edit - forgot to mention i use the spesh footbed, will these fit in other shoes?
