I have a strong and functional foot, and typically use minimalist footwear. I could not wear these all day, for there is too much mass and they are too constricting. But when it comes to pounding the pavement, these conventional running shoes are superior. I feel like I can go all day in them. But once I stop running, I must take them off.much lighter and more comfortable in the arch than the nimbus 23, would definitely buy again!Perfect timing and perfect fitI bought 2 ASICS Noosa Tri 13. One in size 9 and the other in size 9.5. Both feels great. The Nimbus 24 in 9.5 size is too narrow. Only advantage of the Nimbus 24 over the Noosa Tri 13 is the cushioning.I've always loved the Gel Nimbus but the 24 model rubs in all the wrong places. As others have mentioned there is something odd about the tongue and lacing and I end up with blisters on the top of my foot. The heel is also too tight and rubs constantly causing blisters on my heel as well. I've changed sock types and double-socked. I've also tried different lacing styles but nothing works. I've made several attempts at trying to get used to it but end up crawling home and spending days healing. Unless you plan to wrap your foot in an ace bandage before putting this on, avoid the 24 model!Super cómodos la verdad los he usado en varias carreras y super livianos
