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.Order a full size down. These shoes run big. Excellent quality great leather and is expected of Ecco but I wear a size 11 in NB and Nike. The 44 is suppose to be the 10.5 relatable size and was about an inch to long. I got the 9.5 size 43 and that is what fit. Also for those who aren’t aware Ecco golf shoes come with 2 insoles inside. Jelling both in is for normal widget. Removing the top insole turns it into a slightly wider width.really like these shoesMost comfortable golf shoe I have had on my feet. They tend to run a little large. Had to send back the original pair and ordered one size smaller. Perfect fit. Already ordered another pair in a different color. Have worn both pairs a couple of times, including waking 18. As expected from other pairs of ECCO, very water resistant.Hubby's legs ached as usual but his feet, which he has pain issues with, felt really good!! He was very surprised!Usually wear size 9 so I ordered the 43's, too big went to 42's, still too big, hope the 41's fit. Will update when I get them.just a little bit bigger as regular ECCOs. I normally use size EUR 44 and I may get a 43 next time.The shoes were great and wish they would have fit properly. I think I would have needed a size smaller? I would have exchanged but had to buy a pair locally.The fitting of these shoes seems completely different to my other Ecco golf shoes. Had to return these shoes, even though I ordered the exact same size as my other Ecco shoes. These shoes seem slightly larger and I could have lived with that but across the foot as you walk the leather was creasing up as though there was too much leather or badly shaped. Disappointed but if the show fits then they look great otherwise.These shoes are really good. I struggle with width fitting but these come fairly wide and there is a removable insole specifically to make them wider fit. Great quality. The leather is so soft.The Ecco Biom are my favourite golf shoe. From the first time you put them on they fit and feel like a pair of comfortable old slippers! I own a few of these and love them. I have one pair that is over 4 years old - maybe 100 rounds walking up and down the hills of our course on them and they are still comfortable and completely waterproof! These shoes are expensive but I usually watch Amazon for returns. I have enough now that I don't need any new shoes for a while!
