Nike Golf Shoes & Adidas Golf Shoes?
I have a pair of Nike golf shoes that are size 10.5. I saw the Adidas Tour 360 II golf shoes online and I was wondering if I would order the Adidas shoes at a 10.5 or the same size as my Under Armour Proto Speed shoes that are size 12.

I agree with googie, go to a sporting good store and try on a pair of the 360′s you’re looking to buy online. Once you get a size you’re comfortable in, you’ll know right off the bat what size you need.
Helpful tip: Try on shoes towards the end of the day as you’ve been on your feet all day and your feet have expanded to their normal size. Trying on shoes first thing in the morning when you haven’t walked a great deal will give you a false foot size by up to an entire size.
Hope this helps.
I’m with Chef on the trying them on in the afternoon thing. I’m also with the other answerers on the idea of not buying without trying on. Another word of wisdom regarding Nike vs Adidas (from my own personal experience). Nike’s usually are better for folks with narrower feet and lower arches as Adidas shoes have never fit me well, but Nike’s feel like they were made for me. I’m a Nike man, but many people swear by the Three Stripes! Good luck!
Why buy shoes on-line? Isn’t it better to try them on before you buy so that the last, size, heel height and shoe height are comfortable ? Shoes are meant for walking and comfort is the most important aspect of the purchase.
I had Nike 10.5s and have Adidas 10.5s and have no problem. It might be different with you, depending on the shape of your foot, but good luck.
I have to go up 1/2 size on the Addidas.. the 360′s are an excellent choice. The most comfortable golf shoe I have ever owned.
I would go with 11.5, because you seem to have the same foot as me…but if you want to be safe just go with the 12
