Since you possibly have not had enough time thoroughly study the article by Dr. Grigorio Riello to respond to Ms. June Swann's unflattering
review( via Saguto ), I'll add some observations
that may "right" the Riello "mess" a little:
1. The article deals with the innovation and marketing efforts( such as they were in those days) beginning in 1815. Substantial data is offered to identify that AFTER the Napoleonic wars various moves and counter moves were conducted by France & England to win the trade
war by employing footwear style and fashion and
lower price advantages.France paid lower wages and England levied high tariffs to help offset them.
2.Dr. Riello used charts to illustrate the amount of duty charged to keep French footwear out -
1816 to 1819 ... 142% ad valorem

3.A chart shows that only 15% of the imports( to Eng) were boots ( French & other countries combined).
4.That the influx of foreign goods was impacting even the "mere seller of the cheapest sort of article, such as are manufactured in Northampton"-
quote from J.Devlin 1838.
5.The right/left labels issue was plainly dealt with by- " an important competitive advantage for French shoes and was traditionally maintained as a French innovation even after it was applied by English shoemakers ".
6.The ballet shoe type topic Swann critiqued was in the article under the topic of marketing innovation. Dr. Riello gave examples , in this case ballet shoes, of a new neo-classicism fashion that took hold across the continent and those type shoes became part of that fashion. Another example Dr. Riello used in this category was how historians have tended to be "object" oriented and that he was focusing more on the "revolutions in consumption".
Overall, the article seemed to deal fairly with the expose of French advantages and innovations
as they manuvered to gain market-share in England between 1815 and the rest of the early 1800's.
Mr. Cesari, I am sure you can add much more.
