To answer some questions about Connect Toes:
The main difference between CT's and something like Yoga Toes is that CT's are designed to be worn
in shoes, if one chooses to do so. I have some gel rubber toe spreaders that I bought at CVS for $7 and change (you can see the exact one's here
http://www.amazon.com/gp/product/B001M7SIFY/ref=pd_lpo_k2_dp_sr_3?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B000KPP5NC&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1WCTTJ7H00078NF0CEQ4.) By all appearances these Flex-tastic toe spreaders seem similar in size and function to Yoga Toes. To sum up the differences, the Flex-tastics are heavier and thicker than the Connect Toes and seem to spread the toes
slightly further apart. The material seems to be a gel rubber and has a "stickier" feel (meaning its not actually sticky, but it clings to your skin more than the silicone of Connect Toes.) Here are some pictures comparing the profile of these less expensive toe spreaders and Conect Toe's:

So, as you can see, the Connect Toes are much, much thinner and have a lower profile. The Flex-tastics cannot be worn in shoes (I have tried) and it is not comfortable or even really possible to walk comfortable barefoot while wearing them. Connect Toes can be worn in shoes and are quite comfortable to walk normally with while barefoot.
I have also tried the thin disposable toe spreaders that women get after manicures, but I found that they too were nearly impossible to wear with shoes and tended to fold over or squish too much, defeating the purpose. They also stick up too much over the tops of the toes.
I tried wearing the Flex-tastics to bed but because of their size I found it difficult to wear socks over them, and without socks they got caught up in my sheets and wouldn't stay on. They are very noticeable. The best use for them is to wear while lounging around, watching a movie or something- but you'll have to take them off to go get popcorn.
