Seriously. Khajiits and Argonians are Betmer. Beastmen. They don't need any footwear. Because of their animal nature, the need to feel the ground under their soles, their clawed toes...... They must be barefoot.

Khajiits are tradtionally and culturaly a barefoot race. They live and travel all around barefoot. You should respect that. Thanks to their typical and traditional outfits available in the crown shop to give the proof of my words. It'sbarefoot outfits, with just a decorative thin strip around the ankle or between the toes.
Of course, sometimes, they have footwraps too, but their toes are always naked.
What about fighting? Going barefoot to the battle? Why not... ? We are felines. We are souple, flexible, and agile! We practice MARTIAL ARTS! (It's a part of the Khajiit education) Being barefoot is an advantage for dodging and evading (It's exactly why we are better in medium armor). Having naked feet is a strenght for us!
If you're scared to be barefoot, you have the possibility to wear traditionals khajiits feet armor : an armor plate to protect the top of your feet, heel and toes remain naked. You can put these open protections to your feet and remove it quickly. It's more practical than heavy closed boots.
Really, a Khajiit must be barefoot. They don't have to wear boots, shoes, or even sandals!

For Argonians, it's slightly different. Apparently, despite their scaly soles, they wear traditionally sandals. Even their warriors. No closed boot, but sandals. Another proof beastmen don't need heavy closed protection to go in the battle!
But personally, I think Argonians are culturaly a barefoot race too. Using sandals in swamp, bog, or a marsh full of mud and stink-water is not easy. It's why I think they prefer being barefoot. Outside their country, they could have sandals of course, but after living in a swamp, Argonians probably don't care how the ground can be dirty. So, being barefoot is not a problem for them.

But the fact is : Khajiits and Argonians don't need closed boots!

Why are you creating an Argonian or a Khajiit character? Because you like original and lovely animal races. So, you like animal parts of their bodies.In that case, why hidding their feet and their clawed toes into closed boots? Seriously? This doesn't make sense.

All my khajiits characters have naked legs (Mazzatun pants) AND naked feet. And trust me, I'm a solo player, and for solo contents of the game (stories, quests, etc) you can play with a barefoot character, even against world bosses. It's not a problem.

So, what do you think about it, Khajiits and Argonians lovers?
