When designing the Happy Shoes store, we took care to optimize it based on the latest version of PrestaShop software. Thanks to this, the store is fast, individual sub-pages load quickly in the browser window, and navigation is very intuitive. We prepared a dedicated graphic design for the client, along with graphics under RWD, adjusted to browsing the site on mobile devices, and implemented an expanded search engine, so customers can conveniently browse the store's assortment. An OPC module has also been implemented, which streamlines and, above all, measurably facilitates making purchases and finalizing transactions.
