If a manufacturers' excise, or a gross sales tax, or a value- added tax, was shifted along the various chains of production and distribution with no loadage and in such a way that the tax element involved in retail prices was uniformly proportional to retail prices for all commodities and services, its price effects would be identical with those of a retail sales tax.
There is such diversity of footwear in Jazz classes (bare feet, half socks, ordinary socks, running shoes and -even!- Jazz shoes) perhaps check ahead with the class teacher or studio what they prefer their Jazz students to wear on their feet.

If youâre climbing on rand rubber, you will need to replace the rand as well as the sole. Look at the rand. The rand is the strip of rubber around the shoe above the sole. Pay particular attention to the rand on the toe box. It usually gets worn when you scrape the shoe against rock or jam it into cracks. Holes will begin to form in the rand, so you will have to get a replacement rand. Also see if the rand is separating from the upper part of the shoe. Usually the shoe cobbler will squirt glue in the gap to keep the rand and upper together. Also look where the rand and sole meet to see if it is coming apart there.
