With this configuration, the fastening of first eyelet set 121 may be accomplished.
  • In preparation for threading first eyestay 211 and second eyestay 212 of arch strap 200, first portion 311 and second portion 312 may be crossed as first portion 311 and second portion 312 span lacing gap 109. Then, first portion 311 may be inserted into first lower opening 271 of first eyestay 211 and exit through first gap 291. Similarly, second portion 312 may be threaded through second lower opening 272 of second eyestay 212 and exit through third gap 293. Following this threading through a portion of first eyestay 211 and second eyestay 212, first portion 311 and second portion 312 may cross as first portion 311 and second portion 312 span lacing gap 109.
  • After first portion 311 and second portion 312 cross at lacing gap 109, first portion 311 preferably enters third gap 293 to emerge from adjacent fourth gap 294. Likewise, second portion 312 enters first gap 291 to emerge from adjacent second gap 292. Then, in some embodiments, first portion 311 and second portion 312 may be inserted through second eyelet 182 of tongue 118. Following the threading of second eyelet 182 of tongue 118, first portion 311 may be inserted into second gap 292 to re-emerge through first upper opening 273 of first eyestay 211. In a similar manner, second portion 312 may be threaded through fourth gap 294 and emerge from second upper opening 274 of second eyestay 212. With this configuration, lace 108 may fasten arch strap 200.
  • In some embodiments, lace 108 may also be threaded through second eyelet set 122 to further fasten medial lacing portion 110 and lateral lacing portion 111 around a foot. Typically, this may be accomplished by first crossing first portion 311 and second portion 312 as first portion 311 and second 302 span lacing gap 109. Then, first portion 311 and second portion 312 may be threaded through the eyelets comprising second eyelet set 122. Using this configuration, medial lacing portion 110 and lateral lacing portion 111 may be fastened by lace 108.

  • Referring to FIG. 4, foot 400 is inserted into entry hole 103 of article of footwear 100. This allows inner portion 104 of upper 102 to receive foot 400. Once inserted, bottom surface 401 of foot 400 is disposed adjacent to insole 280. Preferably, arch portion 402 of bottom surface 401 is disposed proximate to intermediate portion 203 of arch strap 200. In this embodiment, arch portion 402 is separated from arch strap 200 by insole 280. However, in other embodiments without an insole, arch portion 402 may be disposed directly adjacent to intermediate portion 203. With this arrangement, first end 201 may be disposed on a lateral side of foot 400 and second end 202 may be disposed adjacent to a medial side of foot 400.
  • Preferably, once foot 400 is inserted in article 100, lace 108 may be fastened to secure foot 400 within article 100. Referring to FIG. 5, lace 108 fastens article 100 in a substantially similar manner as the embodiment discussed with respect to FIG. 3. In other embodiments, lace 108 may be fastened through arch strap 200 and eyelets of upper 102 in another manner. With this preferred configuration, lace 108 tightens first eyestay 211 and second eyestay 212 as well as eyelets of upper 102 to secure article 100 around foot 400.
  • Due to the integration of first eyestay 211 and second eyestay 212 with arch strap 200, the fastening of lace 108 tightens insole 280 and arch strap 200 around foot 400. In particular, arch strap 200 may be pulled around arch portion 402 of foot 400 as lace 108 is fastened. In this manner, the fastening of lace 108 causes arch strap 200 to contour to arch portion 402. Specifically, arch strap 200 tightens against a lateral portion and a medial portion of foot 400 when lace 108 is tightened. In some cases, this fastening may also cause insole 280 to partially wrap around a lateral portion and a medial portion of foot 400.
  • Preferably, a wearer may adjust the amount that arch strap 200 is fastened around arch portion 402. Generally, the fastening of arch strap 200 may be adjusted by modifying the tautness of the fastening of lace 108. Using this preferred arrangement, arch strap 200 may be adjusted to provide comfort and support to arch portion 402 of foot 400.
  • In some cases, modifying the fit of arch strap 200 around arch portion 402 allows for some customization of the width of footwear 100. In other words, a wearer may adjust the fastening of lace 108 to achieve different widths for arch portion 402 of foot 400 disposed in article 100. Preferably, fastening lace 108 with a desired tautness allows the wearer to adjust the amount of arch strap 200 available for arch portion 402 of foot 400. In this manner, the fastening of arch strap 200 allows for some customization of the width of footwear 100. In addition, adjusting the tautness of the fastening of lace 108 may alter the amount that insole 280 curves around the sides of foot 400.
  • It is also possible that a wearer may achieve a tighter fit of insole 280 to bottom surface 401 of foot 400 when arch strap 200 is fastened around arch portion 402 of foot 400. This tighter fit preferably creates less friction between foot 400 and insole 280 when the wearer is active. With this preferred arrangement, a wearer may realize a more comfortable fit with insole 280 when arch strap 200 is fastened around foot 400.
  • Preferably, arch strap 200 operates in a similar manner when insole 280 is not used in conjunction with arch strap 200. Without insole 280, arch strap 200 may wrap directly around arch portion 402 of foot 400. In particular, bottom surface 401 may be disposed adjacent to intermediate portion 203 of arch strap 200. In this manner, arch strap 200 may support arch portion 402 when lace 108 fastens first eyestay 211 and second eyestay 212 around foot 400. In some cases, the fastening of arch strap 200 may cause intermediate portion 203 to lift arch portion 402 from a sole of article 100. With this arrangement, arch strap 200 may provide support to arch portion 402 of foot 400.
  • While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims. Also, various modifications and changes may be made within the scope of the attached claims.
