This is my third pair of ECCO Biom G3 Boa. I purchased the first pair in June of last year, they were the previous model using YAK leather and a different lacing systen for the BOA. Those previous shoes were incredibly comfortable. I play a min of 52 rounds a year and usually walk 85% of them. those shoes were great in every way especially stability and comfort. However I suspect the ECCO has had a problem with the previous hardware on the boa lacing system where it connects to the shoe because min broke after 10 months. (This is not a BOA problem). Anyway I sent them back to ECCO under the one year warranty and am awaiting adjudication. Meanwhile I bought these (above) last week. I notice two things the lacing system is different and the leather is no longer the supple YAK leather. I have played three rounds walking with these new ECCOs and I find them to be better, more supportive, even more stable and still as comfortable as the original. They are expensive but your golf swing starts from the ground up and if you are not wearing spikes (soft spikes) then you probably, like me, have issues with your feet being stable at impact. I must wear cleated shoes or I look like a dancing camel falling out of my swing. I think ECCO knows they had a problem with the last model and have done everything to correct and improve this shoe. If and when they credit me for the pair I sent back under warranty I will be purchasing another pair of these. I have not tried the lace up model only the BOA which I find to be a great innovation that keeps the foot stable and secure and does not hurt the top of my feet (high arch).UPDATE within a couple of weeks ECCO credited me $250 towards a replacement pair of Golf Shoes which I have ordered and they are on the way. I bragged to all my golf friends about the excellent customer service. Nice job ECCO I'll shop with you in the future and encourage others to do the same.
