My best guess would be Medium. I wear a size 8.5 shoe and the small size sock fits perfectly

I'm a size 9.5 or 10 and were perfect. But please BE AWARE that it doesn't have to do that much with shoe size but your calf, ankle and thigh circumference. On the third image of this product, a "Fitting Intructions" chart is shown that will guide you on which size you should pick.

I ordered an X-Large 5mm to wear with a size 10 1/2 shoe and the fit is a bit tight. The 5mm thickness is OK for a size 11 men's shoe anything smaller I would suggest the 1.5mm neoprene sock. I've worn both sizes (with different boots) for Washington state surf and salmon fishing; they work great.

I believe that is for a shoe size of 10 through 13. My husband weara an 11 and I bought a large and they fit him well. The best sock ever.

Tough question, I wear a size 11 to 11.5 and I bought size 13. They fit but I wish I would've bought size 14 to accommodate wool socks. I have very wide feet. Min I'd recommend w/normal feet is 11.5 maybe even 12. Warm in northern Minnesota even without wool socks

I wear a size 10 shoe and buy size medium socks. If you go the injinji website it will give a sizing chart.

I ordered size 11 for my normal size 10 rubber shoes and it feels like I'm wearing a size 10.5 and I can still put on a pair of thick socks comfortably. I'd say just add 1 to your normal shoe size because it's better to err with a bigger pair and adjust the difference with the socks or insoles.

I have size 12 feet, I got the XL which fit great. Id say, with 10.5 feet the XL will be just fine, in fact after a few washes will be perfect.

I bought a size 44 for my husband who wears a size 10, so I'm guessing you would probably need a 45.

I went directly to the Injinji website and looked up sizes for M & W, and women's sizing go as follows: Small:6-8.5, M: 9-11.5, L:11-13, XL: 13+. Note the socks come in different weights to where with your Vibram or other sports shoes.

You can check out Under Armour sock sizes on their website sizing chart. I wear a medium and am an 8 1/2 U.S, so you can probably wear 8 to 9 (approximately).

I wear 10.5 and bought mediums - but they are a bit snug. I then bought large and realized that is what I should have been wearing all along. I'd say try a medium, if you have prime order 1 to make sure they fit before spending on something you aren't sure about.

I personally wear a 9.5 men's shoe and the socks I got were medium. Mine fit perfectly. I would think large might be the way to go for a 10.5 especially if his feet are wide.

Well, I have big feet! Size 9.5 - 10 & these socks are snug but they fit fine. They are a bit stretchy too. Hope this helps!!

I am a man and I got the xl. My foot is a 9 and they fit perfect. Probably a lrg or medium. They are sort of one size fits all in some ways because the toes are open. I love these socks. I sleep in them and feet feel awesome in morning.

If you wear a size 10 shoe you should get the large 6-12 size. I wear a size 14 in men's and the extra large sock fits me well!!

John I'm 10.5 and I use L sized. Go to the brand size chart and decide. This are great socks my last use was in th IronMan Cozumel, and it is very good to use this socks in such a long race.
