Are these good for working out?

These socks are very thick, so you may find that they are too hot or too tight in your trainers. I wear them to bed and love them, but I wouldn't consider them for working out.

What is the thickest sock in gold toe womens can you buy? I used to be able to get them at Target but can only find the thinner ones now

I also had searched for the thicker ones, like I had from many years ago. I have found this particular crew sock and also this shorter (quarter) sock to be the thickest. https://www.amazon.com/Gold-Toe-Womens-3-Pack-Ultratec/dp/B007CW12W4/ref=pd_nav_hcs_rp_1/130-5046177-3095603?_encoding=UTF8&pd_rd_i=B007CW12W4&pd_rd_r=734b9e6e-a8d1-4bfd-8e95-63337ef01faf&pd_rd_w=1PuGH&pd_rd_wg=lQCbu&pf_rd_p=769ab71c-2261-43ea-aac5-e1fbe4975570&pf_rd_r=QX8QF4K12KWPPSF4S2PV&psc=1&refRID=QX8QF4K12KWPPSF4S2PV https://www.amazon.com/Gold-Toe-Womens-Ultratec-Qurarter/dp/B0050KICB4/ref=pd_nav_hcs_rp_2/130-5046177-3095603?_encoding=UTF8&pd_rd_i=B0050KICB4&pd_rd_r=9b42dc0b-de03-4546-b933-bb53996b6e35&pd_rd_w=IeBsW&pd_rd_wg=jceXY&pf_rd_p=769ab71c-2261-43ea-aac5-e1fbe4975570&pf_rd_r=KBB38W96ADCH27TY1GZF&psc=1&refRID=KBB38W96ADCH27TY1GZF I hope that helps you.

Do these socks have a flat toe seam or is there a ridge at the toe seam?

There is a toe seam on top of the sock where the gold material meets the white material but it is so flat and unnoticeable that I had to take the sock off to find the seam. I still really like these socks,
