Not really. ""When selecting boots, fine, quality leather will be a wise choice" would be a better substitution. Hope this helps!

I disagree with Erik. It is very common (across Canada, at least) to say high quality materials are an investment. We have a phrase "investing in the future" which is where you do work or spend money now to improve the future. You can say "Buying high quality shoes is a wise investment." Investment does not mean the same as deal, however, especially with the context you provided. Hope this answer helped! :) Good luck with your studies.

Not really. A 'deal ' is an agreement between two parties. When two people settle on a price, or on any other terms regarding the exchange of goods or services, you make a deal. An investment is when you put money into something, hoping to get a good return on this money in the future. This is why the word 'investment' is used here. It means that it is wise to buy good quality leather because it will last well, and you won't need to replace the boots for a very long time. This has nothing at all to do with making a deal with someone.

It's an invvestment if you consider spending more money on better quality items which will last longer instead of cheap items which wont last as long and you will need to replace spending more money in the long run. A "deal" (usually meant as "good deal") means that the price is in the favor of the purchaser. This may be because the item is on sale or is cheaper at a certain vendor compared to another. Hope this helps :)
