the jeep brand is relatively strong and focused. if moved to footwear, think about how this would translate. as a starting point, perhaps identify existing footwear brands/styles that would work as jeep and go from there. Keen, Merrel, ACG? if casual, maybe something along the lines of some of the puma trail stuff?
theres nothing worse than a cobranding that slaps a logo on product. ferrari laptops, anyone? what is the core of the jeep brand? trail? simplicity? mobility? ruggedness? find the core of the brand and you’ll find the core of your concept direction.
also i feel that your rendering is not nearly as strong as the first sketches you posted. maybe suggest to stick with sketches more before going to rendering. also watch your proportions. the jeep stuff looks a bit fat and puffy.
