A cheap suit can make a great impression on people, if a little attention to the details is carried out. Conversely scuffed shoes will make a good suit look unimpressive. To get those shoes shined up, you need a set of brushes and polish. Yes you can use cheap brushes sold in supermarkets, with their nylon bristles. But the finish they give will not be the best, and will take longer to achieve.
Switch to natural brush fibres like these horse hair brushes, and your shoes will shine up quicker, plus the finish you get will be much better. The quality of the brushes is great, and the great lollipop style brush is perfect for application. These brushes are a good investment if personal grooming and appearance is important to you, or you have a job where personal appearance is important.
Other tips for the best shine with brushes:
Use a good quality shoe polish like normal Kiwi shoe polish (brands like 'guardsman gloss' are budget brands that are harder to work into the leather)
Never use 'Parade Gloss' type substances, it contains the wrong mix of ingredients for brush polishing, and produces a greasy finish and is hard to work into the leather.
If your shoes are new, or they need an extra special shine, then a tiny amount of polish on a fingertip worked into the toecaps for 10 mins then given 10 mins hardening/drying time prior to brush polishing will work wonders.
Like polishing the paint finish on a car, the first few layers will be relatively rough, but as you lay up subsequent layers, the finish will get better with each and every layer of polish.
